It is well known that the deformation of the Fe-18 Cr-8 Ni system (SUS304 stainless steel) induces the formation of the martensitic α phase within its parent austenitic γ phase. This martensitic transformation is accompanied by a paramagnetic (γ phase) to ferromagnetic (α phase) transition. This phenomenon has been used to produce a magnetic functionally graded material using an inhomogeneous tensile deformation of a 304 stainless steel. However, detailed knowledge of inhomogeneous deformation behavior is necessary to predict the magnetically graded structure within the specimen. In this study, inhomogeneous deformation behavior of wedge-shaped tensile specimens is studied for SUS304 and SUS310 stainless steels, pure aluminum and pure copper.
