GromovAbstractA 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 °C was carried out. It has been established that the steel/vanadium alloy hybrid obtained by HPT at 20 °C has a higher thermal stability up to a temperature of 700 °C compared to the hybrid obtained by HPT at 400 °C and with hybrid components (steel and vanadium alloy) after HPT at 20 and 400 °C, the thermal stability of which does not exceed 400–450 °C.
