Влияние температуры прокатки на структуру, механизмы деформации и механические свойства стали 01х17н13м3, легированной водородом

Abstract

Chemical-deformation treatment of Fe-17Cr-13Ni-3Mo-0.01C steel leads to refinement of the structure, formation of a high density of twin boundaries and increase in strength properties. Hydrogenation and lowering of rolling temperature both contribute to hardening of the steel, which is caused by a dislocation slip, an increase in the density of twin boundaries and phase transformations. The formation of a strain-induced ε-martensitic phase was observed but their fraction in the structure of steel is low. Lowering of rolling temperature activates an γ-α' transformation, but α'-phase fraction does not exceed 5%.
