Abstract: In grinding SKD-11 hardened steel, the martensite phase transformation is the results of the thermo-mechanical coupled effect and the grind-hardening is highly dependent on the grinding parameters. Special attention is paid to indicating formation mechanism of dark-etching layer and the transition layer to get the desirable hardened surface.

Keywords: hardened steel; grind hardening; hardened layer; dark-etching layer; thermomechanical coupled effect; martensite phase transformation; grinding parameters; formation mechanisms; transition layer; surface hardening.
