Investigating the influence mechanisms of cryogenic treatment on mechanical properties and wear resistance of AISI 4340 steel

This study systematically investigates the multiscale structural evolution of cryogenic treatment processed AISI 4340 steels. It revealed that cryogenic treatment refined martensitic block structures and increased high angle grain boundaries, while reducing martensite tetragonality and matrix carbon...
