The deformation behavior of functionally graded TWIP Steel under monotonic loading at ambient temperature

Abstract

A processing route for the generation of functionally graded parts from steels showing twinning-induced plasticity is proposed. The procedure employing pre-deformation and local heat treatment allows for tailoring local properties with a high degree of freedom. Quasi-static tension tests revealed that no process-induced drawbacks are present, so that functionally graded parts of unprecedented performance become feasible. © 2013 T. Niendorf, C.J. Rüsing, A.
