Russian physics journal Vol. 58, № 2. P. 205-211Abstract: Using the methods of transmission and scanning electron microscopy, the defect substructure of a V–4Ti–4Cr–(C, N, O) alloy dispersion strengthened with nanosized oxicarbonitride particles and the features of its fracture after deformation via active tensile loading at the temperatures 20 and 800°C are investigated. It is shown that the most representative features of deformation at the elevated temperature is primarily activation of grain-boundary mechanisms of deformation and fracture and secondly strain localization accompanied by crystal-lattice re-orientation. The reasons for these phenomena are discussed.
