N2 - Hydrogen desorption behavior associated with γ-α′ and γ-ε martensitic transformation during tensile tests is investigated in four kinds of alloys with different austenite stabilities. Remarkable deformation-induced hydrogen desorption is detected not only as a result of the γ-α′ martensitic transformation, but also because of the γ-ε martensitic transformation, and the amount of desorbed hydrogen from transformed α′ martensite is more than that of transformed ε martensite. This suggests that the solubility of hydrogen in the ε phase is higher than that in the α′ martensite but lower than that in austenite.
