  • A Combined Numerical and Experimental Investigation on Deterministic Deviations in Hot Forging Processes 
    Behrens, Bernd-Arno; Volk, Wolfram; Maier, Daniel; Scandola, Lorenzo; Ott, Michael; Brunotte, Kai; Büdenbender, Christoph; Till, Michael (Amsterdam [u.a.] : Elsevier, 2020)
    In hot forging processes, geometry of the formed workpieces deviate from the desired target geometry, due to complex interactions between tools and billets which result in inhomogeneous temperature and stress fields. The ...
  • Forming and oxidation behavior during forging with consideration of carbon content of steel 
    Graf, Marcel; Ullmann, Madlen; Korpala, Grzegorz; Wester, Hendrik; Awiszus, Birgit; Kawalla, Rudolf; Behrens, Bernd-Arno (Basel : MDPI AG, 2018)
    Developments in technology rely increasingly on the numerical simulation of single process steps up to whole process chains using commercially available or user-written software systems, mostly based on the finite element ...
  • 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 ...
  • 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 ...
