The influences of chromium addition and quenching treatment on the mechanical properties and fracture behaviors of diffusion-alloyed powder metal steels

The addition of Cr and quenching treatment have been found to increase the tensile strength of diffusion-alloyed powder metal steels. However, the influences of these two methods on the impact toughness and fracture behaviors are still unclear. The objective of this study was to clarify the effects of 0.5 wt% Cr and quenching treatment on the mechanical properties and fracture behaviors of diffusion-alloyed powder metal steels under tensile and...
