Simulation of the Forging Process Incorporating Strain-Induced Phase Transformation Using the Finite Volume Method

Abstract

In Part I, based on the framework of metallo-thereto-mechanics, a finite volume method formulated in the Eulerian description has been set up to simulate the forging process and corresponding strain-induced austeniticmartensite phase transformation. The approach has been developed and implemented in the commercial computer program MSC. SuperForge. In this paper, numerical simulations for SUS304 stainless steel on backward and forward extrusions are carried out in order to verify the method proposed in Part I. Furthermore, the effects of strain rate on the austenitic-martensite phase transformation and the aggregate flow stress are studied.
