The authors studied the influence of annealing temperature and degree of cold plastic deformation on the phase-structural condition of alloy V-4Ti-4Cr. By the changing of the lattice period of the vanadium solid solution it was shown that the increase of the annealing temperature to 1400 °С resulted in dissolution of vanadium primary oxicarbonites. Subsequent deformation allows to raise the hardness of the alloy more than twice at the expense of stress aging. Besides, it was revealed that at the degrees of deformation more than 40%, the mechanism of deformation in alloys changes from dislocation to twin.
