The Relation of Low Temperature Deformation and Susceptibility to Hydrogen Embrittlement of Austenitic Stainless Steels.
Abstract
Two candidate materials for cryogenic service, commercial stainless steels 304-L, and 21-6-9, were used for the experiments. These materials were subjected to deformation at various strain rates and temperatures in an attempt to induce partial and/or complete martensitic transformation. The two alloys were then subjected to interrupted tensile tests at various temperatures in which samples were exposed to a cathodic hydrogen charging procedure at various values of tensile pre-strain. Fractographic and metallographic analysis of fractured specimens were performed. The combined effect of hydrogen embrittlement and phase transformation is discussed.
