| Abstract Scope |
Electrically-assisted Manufacturing (EAM) is a newly emerging metal processing technology since it can obtain properties or formability of metals, which cannot be achieved with traditional thermomechanical processes, by applying electric current. Moreover, since the EAM capable of rapid heating can be applied to various processes without any large area or line change in existing processes, it can significantly improve process efficiency. In this study, the tensile deformation behavior of 301L stainless steel containing metastable austenite under pulsed electric current was investigated. The relationship between the mechanically induced martensitic transformation (MIMT) of metastable austenite and pulsed electric current was analyzed by using an X-ray diffractometer (XRD) and a field emission gun scanning electron microscope (FE-SEM) equipped with an electron backscatter diffraction (EBSD). We discussed in detail the effect of pulsed electric current on the elongation in relation to MIMT, reverse transformation and electric current-induced annealing. |
