FCC metals and alloys undergo at low temperatures three distinct phenomena: dynamic strain ageing, plastic strain induced transformation from the parent phase (γ) to the secondary phase () and evolution of micro-damage. Experimental results indicate the correlation between decreasing damage rate and increasing martensite content. In the present paper the constitutive model of the behaviour of stainless steel applied at cryogenic temperature was described, where the three dissipative phenomena coexist. Also the numerical algorithm was worked out, and numerical simulation of uniaxial tension was performed.
