  • Feasibility study for the manufacturing of hybrid pinion shafts with the cross-wedge rolling process 
    Merkel, Paulina; Budde, Laura; Grajczak, Jan; Nowroth, Christian; Prasanthan, Vannila; Kriwall, Mareile; Lammers, Marius; Nothdurft, Sarah; Hermsdorf, Jörg; Twiefel, Jens; Overmeyer, Ludger; Kaierle, Stefan; Wallaschek, Jörg; Breidenstein, Bernd; Behrens, Bernd-Arno; Stonis, Malte (Paris [u.a.] : Springer, 2023)
    The Collaborative Research Center 1153 is investigating an innovative process chain for the production of hybrid components. The hybrid workpieces are first joined and then formed by cross-wedge rolling. Pinion shafts were ...
  • Influence of the Microstructure on Flow Stress and Deformability of Iron-Aluminium Alloys 
    Peddinghaus, Julius; Brunotte, Kai; Wester, Hendrik; Till, Michael; Kock, Christoph; Behrens, Bernd-Arno (Ostrava : TANGER Ltd., 2022)
    Due to their higher weight-specific and high-temperature strength, iron-aluminium alloys have a high potential to replace steel in various applications. The good availability of the two materials, the excellent recyclability, ...
  • Investigation on the microstructure of ecap-processed iron-aluminium alloys 
    Behrens, Bernd-Arno; Brunotte, Kai; Petersen, Tom; Relge, Roman (Basel : MDPI AG, 2021)
    The present work deals with adjusting a fine-grained microstructure in iron-rich iron-aluminium alloys using the ECAP-process (Equal Channel Angular Pressing). Due to the limited formability of Fe-Al alloys with increased ...
  • Investigations on Residual Stresses within Hot-Bulk-Formed Components Using Process Simulation and the Contour Method 
    Behrens, Bernd-Arno; Gibmeier, Jens; Brunotte, Kai; Wester, Hendrik; Simon, Nicola; Kock, Christoph (Basel : MDPI, 2021)
    Residual stresses resulting from hot-forming processes represent an important aspect of a component’s performance and service life. Considering the whole process chain of hot forming, the integrated heat treatment provided ...
  • Production, Bonding and Application of Metal Matrix Composite Hot Forging Tool Components 
    Behrens, Bernd-Arno; Ursinus, Jonathan (Amsterdam [u.a.] : Elsevier, 2020)
    Metal matrix composite materials are of high interest for their increased stiffness, strength or wear resistance. Wear resistant composites contain hard ceramic particles to reduce microcutting and grooving of the metal ...
  • Strategies for residual stress adjustment in bulk metal forming 
    Franceschi, A.; Stahl, J.; Kock, C.; Selbmann, R.; Ortmann-Ishkina, S.; Jobst, A.; Merklein, M.; Kuhfuß, B.; Bergmann, M.; Behrens, B.-A.; Volk, W.; Groche, P. (Berlin ; Heidelberg [u.a.] : Springer, 2021)
    The family of bulk forming technologies comprises processes characterised by a complex three-dimensional stress and strain state. Besides shape and material properties, also residual stresses are modified during a bulk ...
  • Targeted adjustment of residual stresses in hot-formed components by means of process design based on finite element simulation 
    Behrens, B.‐A.; Brunotte, K.; Wester, H.; Kock, C. (Heidelberg [u.a.] : Springer, 2021)
    The aim of this work is to generate an advantageous compressive residual stress distribution in the surface area of hot-formed components by intelligent process control with tailored cooling. Adapted cooling is achieved ...
