摘要: ABSTRACTThe success of deep cryogenic treatment (DCT) austenitic stainless steels (AusSSs) relies heavily on martensitic transformation. For AusSSs that are not prone to transformation, thermomechanical treatments (such as high-temperature solution treatment, plastic deformation, and sensitisation) may expedite DCT by encouraging martensite formation. This paper looks into the influences aforementioned treatability a slightly unstable AusSS regarding tensile properties. Overall, no noticeable strengthening could be achieved through DCT, but slight improvement in ductility was observed for all conditions mentioned above. Preliminary results indicated pitting corrosion resistance almost unaltered DCT.
