Abstract

This study aims to revealing the relationship between retained austenite (RA) morphology, deformation-induced transformation (DIPT) behavior and surface wear behavior. The hardening and fatigue behavior during wear of continuous film-like RA (CFRA), blocky RA (BRA), discontinuous film-like RA (DFRA) and point or flocculent RA (PRA) achieved through different tempering process was investigated using quasi-in-situ fatigue test and impact abrasive wear test. RA morphology exhibited a significant influence on hardening and fatigue behavior during wear. CFRA exhibited the best wear properties, owing to its excellent fatigue performance and hardening capacity. The BRA displayed relative high wear performance, with adequate hardening capacity but weak fatigue performance. DFRA demonstrated comparable wear resistance to BRA due to better fatigue performance. PRA exhibited deficient wear performance due to insufficient fatigue properties and low work hardening ability.
