(S237)Study of Thermal and Mechanical Stability of Retained Austenite (RA) in TRIP Steels

摘要

Transformation-induced plasticity (TRIP) steels containing retained austenite (RA) have the excellentcombination of strength and ductility because TRIP behavior of RA delays the onset of local necking. In orderto take advantage of RA, high volume fraction of RA with adequate stability should be obtained aftermanufacture process such as galvanizing. In this respect, we tried to investigate the thermal and mechanicalstability of RA in present study.
