text: 'Self-piercing riveting is an established joining technique for lightweight
materials. To increase the sustainability of the rivet manufacturing process,
the authors of the present paper have developed an approach for shortening the
process chain by omitting the heat treatment and rivet coating. To do this, use
is made of high nitrogen steel as the rivet material. Successful joining with
these rivets has already been proven, and it has also been shown that a competitive
joint strength can be achieved with these rivets. Up until now, no studies have
been conducted of the corrosion behaviour of uncoated rivets in high nitrogen
steel compared to conventional rivets made of heat-treatable steel with a coating
of Almac® or zinc-nickel with topcoat, and the corrosion behaviour of joints manufactured
with these rivets has also not been investigated. Furthermore, the suitability
of rivets in high nitrogen steel for structures undergoing cathodic dip painting
has not been evaluated to date. These are therefore the aims of the research work
presented in this paper. Corrosion behaviour is tested by exposing rivets and
joints to a salt spray atmosphere. Cross-cut tests are conducted in order to classify
the adhesion of cathodic dip paint to the different rivet surfaces and materials.
The results of the experimental test show that the cathodic dip paint has sufficient
adhesion to the uncoated rivets in high nitrogen steel and that these rivets can
therefore be used in the manufacture of car bodies. Due to the stainless properties
of the high nitrogen steel, better corrosion resistance is seen by comparison
to the commonly used coatings of Almac® and zinc-nickel with topcoat. A study
of the corrosion behaviour of the joints shows that the rivet head diameter and
rivet head position, in particular, are decisive for preventing crevice corrosion
under the rivet head and contact corrosion within the joint. '

text: The use of stainless steel with high strain hardening as material for self-piercing
rivets is a promising approach to shorten the manufacturing process. Due to the
corrosion resistance of the material and the achieved high strength within the
forming process, the heat treatment and the coating can be omitted. As the strength
within the rivet material is achieved by cold forming, the strength distribution
within the rivet remains intact after the manufacturing process. The aim of the
contribution presented is the exploitation of the potential of this strength distribution
to improve the performance of the self-piercing rivets. Therefore, the scope of
the examination is on the analysis of the influence of the local strength on the
deformation behaviour of the rivet during joining. While it is unfeasible to manufacture
rivets with any desired strength distribution, numerical simulation offers an
efficient opportunity to study the effects of varying local strengths. By using
a definable true strain distribution within the rivet as presetting for the simulation,
different strength distributions can be modelled. Through the simulation of the
joining process, the deformation behaviour of the rivet can be examined. Based
on the insights of this analysis, a strength distribution is created that supports
the joining of challenging material combinations consisting of high strength steel
and aluminium. Finally, the approach is verified by experimental joining tests.

text: The sustainability of the manufacturing industry is of special importance
to increase the protection of the environment. The production of fasteners like
self-piercing rivets, however, is costly, time-consuming and energy-intensive.
The heat treatment and the coating, which are mandatory in conventional self-piercing
rivets to achieve adequate strength, ductility and corrosion resistance, are especially
crucial in this respect. Within this paper, an approach for an increase in the
sustainability in fastener production is presented. The use of alternative, high
strain hardening stainless steels as rivet material enables a shortening of the
process chain, because post treatment of the rivets after they are formed can
be omitted. As the change in rivet material and processing causes some issues
along the process chain, the focus of this paper is on the holistic evaluation
of the challenges within the forming of high strain hardening steel and the impact
of the changed rivet properties on the joining result.

text: With regard to environmental protection, the sustainability of production
processes is decisive. Mechanical joining technologies like self-piercing riveting
are of special importance with regard to realising lightweight constructions in
the automotive industry. However, the production of self-piercing rivets is costly,
time-consuming and energy-intensive, as the rivets conventionally must be heat
treated and coated in order to ensure an adequate strength, ductility and corrosion
resistance. Within this paper, it is shown by the example of a newly established
rivet manufacturing process how the sustainability of fastener production can
be increased. The general approach in this context is the use of alternative,
high strain hardening stainless steels as rivet material, which allows the omission
of the post treatment of the rivets after forming. The shortening of the process
chain enables a more sustainable rivet production. Thus, not only the energy consumption
is reduced, but also costs, which is why the novel manufacturing process is also
of interest from an economic point of view.

text: Mechanical joining technologies like self-piercing riveting are gaining importance
with regard to environmental protection, as they enable multi-material design
and lightweight construction. A new approach is the use of high nitrogen steel
as rivet material, which allows to omit the usually necessary heat treatment and
coating and thus leads to a shortening of the process chain. Due to the high strain
hardening, however, high tool loads must be expected. Thus, appropriate forming
strategies are needed. Within this contribution, the influence of applying different
temperatures for each forming stage in a two-stage rivet forming process using
the high nitrogen steel 1.3815 is investigated. The findings provide a basic understanding
of the influence of the temperature management when forming high nitrogen steel.
For this purpose, the rivets are not formed at the same temperature in each stage,
but an elevated temperature is applied selectively. Different process routes are
investigated. First, cups are manufactured in stage 1 at room temperature, followed
by stage 2 at 200°C. Second, cups are formed in stage 1 at 200°C and used for
stage 2 at room temperature. By comparing the findings with results when applying
the same temperature in both stages, it is shown that the temperature during the
first forming operation has an effect on the forming behaviour during the second
forming stage. The required forming forces and the resulting rivet hardness can
be influenced by process-adapted temperature application. Furthermore, the causes
for the temperature impact on the residual cup thickness in stage 1 are evaluated
by a cause and effect analysis, which provides a deeper process understanding.
The thermal expansion of the tool and the billet as well as the improved forming
behaviour at 200°C are identified as the main influencing causes on the achieved
residual cup thickness.

text: Self-piercing riveting is an established technique for joining multi-material
structures in car body manufacturing. Rivets for self-piercing riveting differ
in their geometry, the material used, the condition of the material and their
surface condition. To shorten the manufacturing process by omitting the heat treatment
and the coating process, the authors have elaborated a concept for the use of
stainless steel with high strain hardening as a rivet material. The focus of the
present investigation is on the evaluation of the influences of the rivet’s geometry
and material on its deformation behaviour. Conventional rivets of types P and
HD2, a rivet with an improved geometry made of treatable steel 38B2, and rivets
made of the stainless steels 1.3815 and 1.4541 are examined. The analysis is conducted
by means of multi-step joining tests for two material combinations comprising
high-strength steel HCT70X and aluminium EN AW-5083. The joints are cut to provide
a cross-section and the deformation behaviour of the different rivets is analysed
on the basis of the measured changes in geometry and hardness. In parallel, an
examination of the force-stroke curves provides further insights. It can be demonstrated
that, besides the geometry, the material strength, in particular, has a significant
influence on the deformation behaviour of the rivet. The strength of steel 1.4541
is seen to be too low for the joining task, while the strength of steel 1.3815
is sufficient, and hence the investigation confirms the capability of rivets made
of 1.3815 for joining even challenging material combinations.

text: 'The use of high-strength steel and aluminium is rising due to the intensified
efforts being made in lightweight design, and self-piercing riveting is becoming
increasingly important. Conventional rivets for self-piercing riveting differ
in their geometry, the material used, the condition of the material and the coating.
To shorten the manufacturing process, the use of stainless steel with high strain
hardening as the rivet material represents a promising approach. This allows the
coating of the rivets to be omitted due to the corrosion resistance of the material
and, since the strength of the stainless steel is achieved by cold forming, heat
treatment is no longer required. In addition, it is possible to adjust the local
strength within the rivet. Because of that, the authors have elaborated a concept
for using high nitrogen steel 1.3815 as the rivet material. The present investigation
focusses on the joint strength in order to evaluate the capability of rivets in
high nitrogen steel by comparison to conventional rivets made of treatable steel.
Due to certain challenges in the forming process of the high nitrogen steel rivets,
deviations result from the targeted rivet geometry. Mainly these deviations cause
a lower joint strength with these rivets, which is, however, adequate. All in
all, the capability of the new rivet is proven by the results of this investigation. '

text: The number of multi-material joints is increasing as a result of lightweight
design. Self-piercing riveting (SPR) is an important mechanical joining technique
for multi-material structures. Rivets for SPR are coated to prevent corrosion,
but this coating also influences the friction that prevails during the joining
process. The aim of the present investigation is to evaluate this influence. The
investigation focuses on the common rivet coatings Almac® and zinc-nickel with
topcoat as well as on uncoated rivet surfaces. First of all, the coating thickness
and the uniformity of the coating distribution are analysed. Friction tests facilitate
the classification of the surface properties. The influence of the friction on
the characteristic joint parameters and the force-stroke curves is analysed by
means of experimental joining tests. More in-depth knowledge of the effects that
occur is achieved through the use of numerical simulation. Overall, it is shown
that the surface condition of the rivet has an impact on the friction during the
joining process and on the resulting joint. However, the detected deviations between
different surface conditions do not restrict the operational capability of SPR
and the properties of uncoated rivet surfaces, in particular, are similar to those
of Almac®-coated rivets. It can thus be assumed that SPR with respect to the joining
process is also possible without rivet coating in principle.

text: The aim to reduce pollutant emission has led to a trend towards lightweight
construction in car body development during the last years. As a consequence of
the resulting need for multi-material design, mechanical joining technologies
become increasingly important. Mechanical joining allows for the combination of
dissimilar materials, while thermic joining techniques reach their limits. Self-piercing
riveting enables the joining of dissimilar materials by using semi-tubular rivets
as mechanical fasteners. The rivet production, however, is costly and time-consuming,
as the rivets generally have to be hardened, tempered and coated after forming,
in order to achieve an adequate strength and corrosion resistance. A promising
approach to improve the efficiency of the rivet manufacturing is the use of high-strength
high nitrogen steel as rivet material because these additional process steps would
not be necessary anymore. As a result of the comparatively high nitrogen content,
such steels have various beneficial properties like higher strength, good ductility
and improved corrosion resistance. By cold bulk forming of high nitrogen steels
high-strength parts can be manufactured due to the strengthening which is caused
by the high strain hardening. However, high tool loads thereby have to be expected
and are a major challenge during the production process. Consequently, there is
a need for appropriate forming strategies. This paper presents key aspects concerning
the process design for the manufacturing of semi-tubular self-piercing rivets
made of high-strength steel. The aim is to produce the rivets in several forming
stages without intermediate heat treatment between the single stages. Due to the
high strain hardening of the material, a two stage forming concept will be investigated.
Cup-backward extrusion is chosen as the first process step in order to form the
rivet shank without forming the rivet foot. Thus, the strain hardening effects
in the area of the rivet foot are minimized and the tool loads during the following
process step can be reduced. During the second and final forming stage the detailed
geometry of the rivet foot and the rivet head is formed. In this context, the
effect of different variations, for example concerning the final geometry of the
rivet foot, on the tool load is investigated using multistage numerical analysis.
Furthermore, the influence of the process temperature on occurring stresses is
analysed. Based on the results of the investigations, an adequate forming strategy
and a tool concept for the manufacturing of semi-tubular self-piercing rivets
made of high-strength steel are presented.

text: As a result of lightweight design, increased use is being made of high-strength
steel and aluminium in car bodies. Self-piercing riveting is an established technique
for joining these materials. The dissimilar properties of the two materials have
led to a number of different rivet geometries in the past. Each rivet geometry
fulfils the requirements of the materials within a limited range. In the present
investigation, an improved rivet geometry is developed, which permits the reliable
joining of two material combinations that could only be joined by two different
rivet geometries up until now. Material combination 1 consists of high-strength
steel on both sides, while material combination 2 comprises aluminium on the punch
side and high-strength steel on the die side. The material flow and the stress
and strain conditions prevailing during the joining process are analysed by means
of numerical simulation. The rivet geometry is then improved step-by-step on the
basis of this analysis. Finally, the improved rivet geometry is manufactured and
the findings of the investigation are verified in experimental joining tests.

text: Due to the trend towards lightweight design in car body development mechanical
joining technologies become increasingly important. These techniques allow for
the joining of dissimilar materials and thus enable multi-material design, while
thermic joining methods reach their limits. Semi-tubular self-piercing riveting
is an important mechanical joining technology. The rivet production, however,
is costly and time-consuming, as the process consists of several process steps
including the heat treatment and coating of the rivets in order to achieve an
adequate strength and corrosion resistance. The use of high nitrogen steel as
rivet material leads to the possibility of reducing process steps and hence increasing
the efficiency of the process. However, the high tool loads being expected due
to the high strain hardening of the material are a major challenge during the
rivet production. Thus, there is a need for appropriate forming strategies, such
as the manufacturing of the rivets at elevated temperatures. Prior investigations
led to the conclusion that forming already at 200 °C results in a distinct reduction
of the yield strength. To create a deeper understanding of the forming behaviour
of high nitrogen steel at elevated temperatures, compression tests were conducted
in a temperature range between room temperature and 200 °C. The determined true
stress – true strain curves are the basis for the further process and tool design
of the rivet production. Another key factor for the rivet manufacturing at elevated
temperatures is the influence of the process temperature on the tribological conditions.
For this reason, ring compression tests at room temperature and 200 °C are carried
out. The friction factors are determined on the basis of calibration curves resulting
from the numerical analysis of the ring compression process. The investigations
indicate that the friction factor at 200 °C is significantly higher compared to
room temperature. This essential fact has to be taken into account for the process
and tool design for the rivet production using high nitrogen steel.
