  • Phenomenological modeling of anisotropy induced by evolution of the dislocation structure on the macroscopic and microscopic scale 
    Clausmeyer, Till; van den Boogaard, Ton; Noman, Muhammad; Gershteyn, Grygoriy; Scharper, Mirko; Svendsen, Bob; Bargmann, Swantje (Heidelberg : Springer Verlag, 2011)
    This work focuses on the modeling of the evolution of anisotropy induced by the development of the dislocation microstructure. A model formulated at the engineering scale in the context of classical metal plasticity and a ...
  • Properties and application of high-manganese TWIP-steels in sheet metal forming 
    Busch, Christian; Hatscher, Ansgar; Otto, Manuel; Huinink, Stefan; Vucetic, Milan; Bonk, Christian; Bouguecha, Anas; Behrens, Bernd-Arno (Amsterdam : Elsevier, 2014)
    Within this work uniaxial tensile tests have been performed with high-manganese TWIP-steel and different dual-phase steels to determine mechanical properties. The transfer of the results form uniaxial tensile tests to ...
  • Residual stresses in grinding of forming tools with toric grinding pins 
    Grove, Thilo; Lucas, Henning; Denkena, Berend (Amsterdam : Elsevier B.V., 2018)
    The subsurface residual stress state of forming tools is an important factor for the lifetime of these tools. This is especially important for tools used in processes like sheet-bulk metal forming, where very high process ...
  • Selective oxidation of tool steel surfaces under a protective gas atmosphere using inductive heat treatment 
    Schöler, S.; Yilkiran, D.; Wulff, D.; Özkaya, F.; Möhwald, K.; Behrens, Bernd-Arno; Maier, H.J. (Les Ulis : EDP Sciences, 2018)
    For the realization of liquid lubricant free forming processes different approaches are conceivable. The priority program 1676 "Dry forming - Sustainable production through dry machining in metal forming" addresses this ...
  • Shortening tool setting time for transfer presses 
    Behrens, Bernd-Arno; Doege, E.; Krimm, R. (London : SAGE Publications Ltd., 2006)
    The production processes of sheet metal products with complex geometries often use transfer presses to obtain fully formed workpieces from a single machine. The job of adjusting a new multistage tool set increases with the ...
  • Weakening of thick steel plates by laser radiation for the removal of hazardous substances 
    Hoff, Christian; Hermsdorf, Jörg; Kaierle, Stefan; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2018)
    Hazardous substances such as unexploded ordnance represent a serious threat. It is necessary to develop new methods and equipment for their elimination. For this reason, a laser ablation process is developed where the shell ...
  • Wear Behavior of MoS2 Lubricant Layers during Sheet Metal Forming 
    Behrens, Bernd-Arno; Maier, Hans Jürgen; Hübner, Sven; Bonk, Christian; Almohallami, Amer; Lummer, Christin; Schein, Patrick; Scheland, Hannes; Micke-Camuz, Moritz (London : Elsevier Ltd., 2017)
    The increased use of high and ultra-high strength steel and materials with a high adhesion tendency leads to higher demands regarding the wear resistance of forming tools. A promising approach addressing both challenges ...
  • Wear investigation of selective α-Fe2O3 oxide layers generated on surfaces for dry sheet metal forming 
    Behrens, Bernd-Arno; Yilkiran, Deniz; Schöler, Simon; Özkaya, Fahrettin; Hübner, Sven; Möhwald, Kai (Amsterdam : Elsevier B.V., 2018)
    To realize a dry sheet metal forming process, α-Fe 2 O 3 oxide layers were investigated regarding their friction characteristics, wear behavior and surface energy depending on different surface qualities of the specimens ...
