Enhancing Deep Drawing Processes by Using a Thermomechanical Tool Design

Abstract:

The nature of phase transformation in metastable austenitic steels due to strain- induced ’-martensite formation is used as new contribution to lightweight construction in crash safety applications. A thermomechanical tool design was developed to enhance the ’-martensite evolution in local areas. Draw and stop beads allow a concerted stretch-out of material by increasing true strain . The local warming of defined regions avoids the phase transformation to retain the original austenitic lattice while a regional cooling enforce this nature by realizing a constant true strain .
