text: "Abstract\r\n This paper presents
the characterization of the microstructure evolution during flow forming of austenitic
stainless steel AISI 304L. Due to plastic deformation of metastable austenitic
steel, phase transformation from γ-austenite into α’-martensite occurs. This is
initiated by the formation of shear bands as product of the external stresses.
By means of coupled microscopic and micromagnetic investigations, a characterization
of the microstructure was carried out. In particular, this study shows the distribution
of the strain-induced α’-martensite and its influence on material properties like
hardness at different depths. The microstructural analyses by means of electron
backscattered diffraction (EBSD) technique, evidence a higher amount of α’-martensite
(ca. 23 %) close to the outer specimen surface, where the plastic deformation
and the direct contact with the forming tool take place. In the middle area (ca.
1.5 mm depth from the outer surface), the portion of transformed α’-martensite
drops to 7 % and in the inner surface to 2 %. These results are well correlated
with microhardness and micromagnetic measurements at different depths. EBSD and
atomic force microscopy (AFM) were used to make a detailed characterization of
the topography and degree of deformation of the shear bands. Likewise, the mechanisms
of nucleation of α’-martensite were discussed. This research contributes to the
development of micromagnetic sensors to monitor the evolution of properties during
flow forming. This makes them more suitable for closed-loop property control,
which offers possibilities for an application-oriented and more efficient production."

text: The production of complex multi-functional, high-strength parts is
becoming increasingly important in the industry. Especially with small batch size,
the incremental flow forming processes can be advantageous. The production of
parts with complex geometry and locally graded material properties currently depicts
a great challenge in the flow forming process. At this point, the usage of closed-loop
control for the shape and properties could be a feasible new solution. The overall
aim in this project is to establish an intelligent closed-loop control system
for the wall thickness as well as the α’-martensite content of AISI 304L-workpieces
in a flow forming process. To reach this goal, a novel sensor concept for online
measurements of the wall thickness reduction and the martensite content during
forming process is proposed. It includes the setup of a modified flow forming
machine and the integration of the sensor system in the machine control. Additionally,
a simulation model for the flow forming process is presented which describes the
forming process with regard to the plastic workpiece deformation, the induced
α’-martensite fraction, and the sensor behavior. This model was used for designing
a closed-loop process control of the wall thickness reduction that was subsequently
realized at the real plant including online measured feedback from the sensor
system.

text: Mechanical joining processes are an essential part of modern lightweight construction.
They permit materials of different types to be joined in a way that is suitable
for the loads involved. These processes reach their limits, however, as soon as
the boundary conditions change. In most cases, these elements are specially adapted
to the joining point and cannot be used universally. Changes require cost-intensive
adaptation of both the element and the process control, thus making production
more complex. This results in high costs due to the increased number of auxiliary
joining element variants required and reduces the economic efficiency of mechanical
joining. One approach to overcoming this issue is the use of adaptive auxiliary
joining elements formed by friction spinning. This article presents the current
state of research on pre-hole-free joining with adaptive joining elements. The
overall process chain is illustrated, explained and analyzed. Special attention
is paid to demonstrating the feasibility of pre-hole-free joining with adaptive
joining elements. The chosen mechanical parameters are subsequently listed. Finally,
a comprehensive outlook of the future development potential is derived.

text: Higher quality requirements by customers demand higher precision and
accuracy from manufacturing processes. Application oriented preparation of semi-finished
materials is key for subsequent forming operations, therefore, straightening machines
are employed. Straightening strengthens the material by increasing plastic deformation
by means of strain hardening, resulting in undesirable reduction in formability
when processing high strength materials, in particular. Conventional roll-type
straightening machines process either bars or strips. This is achieved upon passing
material between rolls arranged in two staggered rows. However, conventional straightening
processes do not adapt to the local varying distortion of coiled strips. Innovative,
self-correcting process control techniques, which adapt to the initial geometric
characteristics of the strip, present a promising approach to fix this issue through
optimization of the leveling process. Here, an innovative strategy to improve
straightening of high strength steel materials (1.4310) is presented. This implements
optimized leveling, adding minimal plastic deformation and, thus, strain hardening.
To operate an intelligent straightening machine, a reliable online measurement
of the surface defects is fundamentally essential. The MagnaTest, which is developed
for material testing, is made feasible for such purposes after calibrating for
curvature measurement. Preliminary results are promising in regards to measuring
the curvature online, so that the following straightening process can be close
loop controlled. The bending measurement is linked to open/closed loop control,
therefore providing an optimal straightening result in regards to formability,
leveling, and reduced strain hardening.

text: Nowadays, the production of modern lightweight structures, like a body in
white structure requires a wide variety of mechanical joining processes. To fulfill
the various demands, mechanical joining processes and joining elements (JE) are
used. Very often, they are adapted to the application, which leads in turn to
a numerous of different variants, high costs, and loss of the process chain versatility.
To overcome this drawback, an innovative approach is the usage of individually
produced and task-adapted JE, the so-called friction spun joint connectors (FSJC).
These connectors can be modified in shape as well as in material properties. This
flexibility offers high potential for lightweight design but also increases the
necessary analytical effort regarding the forming process as well as the manufactured
joint's properties. Therefore, a new analysis strategy based on the Finite-Element-Method
(FEM) is proposed, which numerically determines the local load bearing capacity
within a given joint in order to identify the critical regions for load transfer.
The process of joining element manufacturing and the analysis strategy will be
described in detail and optimization results of the joints are shown. Numerical
results are discussed and possible recommendations for joint manufacturing are
derived.

text: The implementation of control systems in metal forming processes improves
product quality and productivity. By controlling workpiece properties during the
process, beneficial effects caused by forming can be exploited and integrated
in the product design. The overall goal of this investigation is to produce tailored
tubular parts with a defined locally graded microstructure by means of reverse
flow forming. For this purpose, the proposed system aims to control both the desired
geometry of the workpiece and additionally the formation of strain-induced α′-martensite
content in the metastable austenitic stainless steel AISI 304 L. The paper introduces
an overall control scheme, a geometry model for describing the process and changes
in the dimensions of the workpiece, as well as a material model for the process-induced
formation of martensite, providing equations based on empirical data. Moreover,
measurement systems providing a closed feedback loop are presented, including
a novel softsensor for in-situ measurements of the martensite content.

text: Modern forming processes often allow today the efficient production
of complex parts. In order to increase the sustainability of forming processes
it would be favorable if the forming of workpieces becomes possible using production
waste. At the Chair of Forming and Machining Technology of the Paderborn University
(LUF) research is presently conducted with the overall goal to produce workpieces
directly from secondary aluminum (e.g., powder and chips). Therefore, friction-based
forming processes like friction spinning (or cognate processes) are used due to
their high efficiency. As a pre-step, the production of semi-finished parts was
the subject of accorded research work at the LUF. Therefore, a friction-based
hot extrusion process was used for the full recycling or rework of aluminum chips
into profiles. Investigations of the recycled semi-finished products show that
they are comparable to conventionally produced semi-finished products in terms
of dimensional stability and shape accuracy. An analysis of the mechanical properties
of hardness and tensile strength shows that a final product with good and homogeneously
distributed properties can be produced. Furthermore, significant correlations
to the friction spinning process could be found that are useful for the above-mentioned
direct part production from secondary aluminum.

- lang: eng
text: One of the main objectives of production engineering is to reproducibly manufacture
(complex) defect-free parts. To achieve this, it is necessary to employ an appropriate
process or tool design. While this will generally prove successful, it cannot,
however, offset stochastic defects with local variations in material properties.
Closed-loop process control represents a promising approach for a solution in
this context. The state of the art involves using this approach to control geometric
parameters such as a length. So far, no research or applications have been conducted
with closed-loop control for microstructure and product properties. In the project
on which this paper is based, the local martensite content of parts is to be adjusted
in a highly precise and reproducible manner. The forming process employed is a
special, property-controlled flow-forming process. A model-based controller is
thus to generate corresponding correction values for the tool-path geometry and
tool-path velocity on the basis of online martensite content measurements. For
the controller model, it is planned to use a special process or microstructure
(correlation) model. The planned paper not only describes the experimental setup
but also presents results of initial experimental investigations for subsequent
use in the closed-loop control of α’-martensite content during flow-forming.
