Achieving enhanced cryogenic toughness in a 1 GPa grade HSLA steel through reverse transformation of martensite

Achieving enhanced cryogenic toughness in a 1 GPa grade HSLA steel through reverse transformation of martensite

The effect of microstructure on crack resistance and cryogenic toughening in a 3.5 wt% Ni high-strength low-alloy (HSLA) steel was investigated. Multistage heat treatments involving quenching (Q), lamellarization (L), and tempering (T) were applied to prepare the HSLA steels with various microstruct...
