A novel Si-Al alloyed press hardening steel(PHS)with the ferrite(α)-austenite(γ)-martensite(α')triplex microstructure was developed to have marginal oxidization after the hot forming in air,and the resultant ultima...

In this paper, we report the influence of cooling processes on the yielding behavior of a medium Mn steel(MMS) with triplex microstructure, i.e. austenite(γ), ferrite(α) and as-quenched martensite(α’). After the i...
