High thermally stable multi-layer steel/vanadium alloy hybrid material obtained by high-pressure torsion

Abstract

Abstract A comparative analysis of the thermal stability of the steel/vanadium alloy hybrid material and its components (steel type AISI 439 and V–10Ti–5Cr alloy) obtained by high-pressure torsion (HPT) at 20 and 400\u202f°C was carried out. It has been established that the steel/vanadium alloy hybrid obtained by HPT at 20\u202f°C has a higher thermal stability up to a temperature of 700\u202f°C compared to the hybrid obtained by HPT at 400\u202f°C and with hybrid components (steel and vanadium alloy) after HPT at 20 and 400\u202f°C, the thermal stability of which does not exceed 400–450\u202f°C.
