TITLE
Plastic Strain Induced Martensite in a Type 304 Austenitic Stainless Steel. Modelling and Numerical Simulation of Deep Drawing Processes

ABSTRACT
In this paper, a strain-induced martensitic transformation kinetics model and some new constitutive equations of type 304 stainless steel materials are proposed. The classical transformation phase from austenite () to martensite (') at a high plastic deformation and/or at low temperature is the basic reaction in this material hardening. However, this transformation may play an important role in the mechanical working. Particularly on strain and stress distribution in a deformed cup obtained by a deep drawing process. A Finite Element Analysis (FEA) in the deep drawing processes is conducted under different environmental temperatures. A validity of the proposed constitutive equations is then discussed and a good agreement with experimental work was found.
