Application effect of cryogenic process 1. Effect of different cryogenic treatment processes on retained austenite in w6cr5mo4v2co steel (volume percent) In the process of cryogenic treatment, a large amount of retained austenite transforms into martensite, especially the supersaturated metastable martensite will decrease the supersaturation during the process from – 196 ° C to room temperature,… Read more Application effect of cryogenic process
