Аннотация
The evolution of the structure and the hardness of single-phase Ni–Cr alloys with 2–12.5 at % Cr is studied during high-pressure torsion. It is established that the hardness of the alloys, unlike pure nickel, continuously increases in the entire true strain range 0.2–12. Alloying with chromium is shown to substantially inhibit the formation of a submicrocrystalline structure and to enhance the refinement of microcrystallites.
