he obtained results shown that the HCP ε-FeMn alloy of the Fe-20 %Mn-0.05 %C type deformed by HE undergoes brittle DF along the boundaries of initial austenitic grains. A decreased resistance of alloy extrudates to DF is due to a high-intensive γ→ε-MT with a certain stabilization of ε→α′, especially in the zone of rupture. This results in the lowering of relaxation stability of the alloy. The optimal regime of hardening by HE is deformation to a ε≂30–40 %, which provides the improvement of mechanical properties in complex and the increase in the resistance to DF. It is shown that the induced to a considerable degree by hydrogen degradation of the structural strength of HCP ε-FeMn alloys is a complex problem for material science, chemistry and mechanics of metallic materials.
