Which of the following processes permits the transformation of austenite to martensite, throughout the crosssection of a component without cracking or distortion?
Marquenching
Marquenching addresses this issue by quenching the steel into a medium held just above the M_s temperature. Based on the analysis, Marquenching is the process designed to achieve a martensitic structure throughout the cross-section of a component while minimizing cracking and distortion.
