抜粋

To suppress hydrogen permeation from environment into cold-worked high strength austenitic stainless steel, the surface heat treatment using high-frequency induction heating was applied to a cord-drawn metastable austenitic stainless steel (Fe-16Cr-10Ni alloy). By this heat treatment, the microstructure in the surface-layer (1mm depth) was controlled to austenite, while the inside of the material was strengthened by a large fraction of deformation-induced martensite. TDS analysis for the cathodically charged specimen revealed that hydrogen permeation was significantly retarded and no diffusible hydrogen existed. These results suggest that hydrogen embrittlement can be avoided by covering the material surface with austenite phase even in cold-worked high strength austenitic stainless steel.
