Phase Transformation and Deformation Model for Quenching Simulations

Y. Kaymak [1],
[1] VDEh Betriebsforschungsinstitute GmbH, Düsseldorf, Germany

Heat treatment of the advanced steel grades (like micro-alloyed steels or AHSS steel grades) is a challenging process as the residual stress/deformation are very pronounced and the customer quality requirements are getting stricter. Instead of a trial and error based process control, a ... Read More
