text: AbstractDifferent studies have been demonstrated
that the surface integrity of substrate bulk materials to be coated has a significant
impact on the adhesion of thermally sprayed coatings. It is known that the surface
integrity of parts processed by selective laser melting (SLM) differs from those
obtained from bulk materials. Although 316L stainless steel is among the most
investigated material for SLM, the adhesion of thermally sprayed coatings on 316L
stainless steel substrates processed by SLM has not been studied yet. This study
aims at evaluating the effect of various mechanical pre-treatments onto 316L stainless
steel substrates processed by SLM and their effect on the adhesion of high velocity
oxy-fuel (HVOF)-sprayed WC-Co coatings. To differentiate between topographical
effects and residual stress-related phenomena, a stress-relief heat treatment
of the SLM substrates served as a reference throughout the investigations. The
differently pre-treated SLM substrates were investigated with regard to the surface
roughness and residual stresses. For the HVOF-sprayed SLM composites, Vickers
interfacial indentation tests were conducted to assess the resulting coating adhesion.
The findings demonstrated that the HVOF-sprayed WC-Co coatings predominantly exhibit
good adhesion to the SLM 316L substrates. However, it was found that the stress
state in the SLM 316L substrate surface is more likely to affect the adhesion
of the WC-Co coating, while the substrate surface roughness showed a marginal
effect.

text: Ultrasonic wire bonding is a process to form electrical connections in electronics
well established industry. Typically, a clamping tool is pressed on the wire and
forced to vibrate at relative high frequency 40 to 100 kHz. The ultrasonic vibration
is transmitted through the wire into the interface between wire and substrate.
Due to frictional processes, contamination like oxide layers are removed from
the contact zone, the surface roughness is reduced, and with increasing bond duration
an metallic connection of wire and substrate is established. It is known that
the amount of ultrasonic energy over time directly influences the strength and
reliability of the bond connection, but the determination of optimum bond parameters
is still a challenging experimental task. For this, in the past different model
approaches have been presented, to calculate the bond quality by simulation. Measuring
the friction between wire and substrate to validate these models is a challenging
task at ultrasonic bonding frequency. Therefore a versatile test rig for bonding
experiments at frequencies lower than 1 kHz is setup to get detailed insight into
the different phases of the connection process. It includes a piezoelectric force
sensor for the measurement of the three-dimensional process forces, an electrodynamic
shaker for the vibration excitation and a conventional tension-compression testing
machine to apply the bond normal force. Using this test rig, it is possible to
observe the different phases of bond formation in detail, validate and enhance
existing models and finally optimize bond parameters for different processes.

text: In all fields, the significance of a reliable and accurate predictive model
is almost unquantifiable. With deep domain knowledge, models derived from first
principles typically outperforms other models in terms of reliability and accuracy.
When it may become a cumbersome or an unachievable task to build or validate such
models of complex (non-linear) systems, machine learning techniques are employed
to build predictive models. However, the accuracy of such techniques is not only
dependent on the hyper-parameters of the chosen algorithm, but also on the amount
and quality of data. This paper investigates the application of classical time
series forecasting approaches for the reliable prognostics of technical systems,
where black box machine learning techniques might not successfully be employed
given insufficient amount of data and where first principles models are infeasible
due to lack of domain specific data. Forecasting by analogy, forecasting by analytical
function fitting, an exponential smoothing forecasting method and the long short-term
memory (LSTM) are evaluated and compared against the ground truth data. As a case
study, the methods are applied to predict future crack lengths of riveted aluminium
plates under cyclic loading. The performance of the predictive models is evaluated
based on error metrics leading to a proposal of when to apply which forecasting
approach.

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.
