Adjusting Mechanical Properties of Forging Dies Produced by Ausforming

Behrens, Bernd-Arno; Brunotte, Kai; Petersen, Tom; Ostermeyer, Corvin; Till, Michael (Liège : ULiège Library, 2021)

Due to high thermo-mechanical loads, tools used in hot forming operations need a high resistance to different damage phenomena, such as deformation, cracking and abrasion. They are exposed to cyclic thermo-mechanical stress ...
Analysis of machine influence on process stability in sheet bulk metal forming

Salfeld, Valerian; Matthias, Tim; Krimm, Richard; Behrens, Bernd-Arno (Amsterdam : Elsevier BV, 2012)

This contribution deals with the process-machine interaction while forming parts by sheet-bulk metal forming. The goal of this process is to form complex functional elements, such as gearing and carrier elements, by means ...
Design, setup, and evaluation of a compensation system for the light deflection effect occurring when measuring wrought-hot objects using optical triangulation methods

Quentin, Lorenz; Reinke, Carl; Beermann, Rüdiger; Kästner, Markus; Reithmeier, Eduard (Basel : MDPI AG, 2020)

In this paper, we present a system to compensate for the light deflection effect during the optical geometry measurement of a wrought-hot object. The acquired 3D data can be used to analyze the formed geometry of a component ...
Development of a numerical compensation framework for geometrical deviations in bulk metal forming exploiting a surrogate model and computed compatible stresses

Scandola, Lorenzo; Büdenbender, Christoph; Till, Michael; Maier, Daniel; Ott, Michael; Behrens, Bernd-Arno; Volk, Wolfram (Paris [u.a.] : Springer, 2021)

The optimal design of the tools in bulk metal forming is a crucial task in the early design phase and greatly affects the final accuracy of the parts. The process of tool geometry assessment is resource- and time-consuming, ...
Functionalisation of the Boundary Layer by Deformation-Induced Martensite on Bearing Rings by means of Bulk Metal Forming Processes

Behrens, Bernd-Arno; Brunotte, Kai; Wester, Hendrik; Peddinghaus, Julius; Till, Michael (Ostrava : TANGER Ltd., 2022)

During cold forming of metastable austenitic steels, a strength-increasing phase transformation induced by externally superimposed stresses occurs in addition to strain hardening. The effect of deformation-induced martensite ...
Influence of Cooling Parameters on the Surface Layer Structure of Hot Working Tools

Behrens, Bernd-Arno; Brunotte, Kai; Peddinghaus, Julius; Lorenz, Uwe (Ostrava : TANGER Ltd., 2022)

The surface layer of hot working tools is subject to alternating thermo-mechanical loads during forging. It experiences a fast increase in temperature on contact with the heated billets, followed by a steep temperature ...
Introduction to tailored forming

Behrens, B.-A.; Uhe, J. (Heidelberg : Springer, 2021)

In recent years, the requirements for technical components have been increasing steadily. This development is intensified by the desire for products with lower weight, smaller size and extended functionality, but at the ...
Numerical investigations regarding a novel process chain for the production of a hybrid bearing bushing

Behrens, Bernd-Arno; Maier, Hans Jürgen; Poll, Gerhard; Wriggers, Peter; Aldakheel, Fadi; Klose, Christian; Nürnberger, Florian; Pape, Florian; Böhm, Christoph; Chugreeva, Anna; Coors, Tim; Duran, Deniz; Thürer, Susanne E.; Herbst, Sebastian; Hwang, Jae-Il; Matthias, Tim; Heimes, Norman; Uhe, Johanna (Heidelberg : Springer, 2020)

This contribution deals with the numerical investigations to develop a novel process chain for hybrid solid components using Tailored Forming. For manufacturing a hybrid bearing bushing, co-extrusion is the first step to ...
