摘要：
The empirical and semi-empirical models were used to analyze the phase-structural state of lightweight alloys of the Ti-Cr-Al-V system. The composition of lightweight alloy Ti 61 Cr 10 Al 7 V 22 (at.%) was selected for experimental study. Ingots of this alloy were obtained by argon-arc melting method, and they were subjected to homogenization, deformation by rolling and subsequent annealing at different temperatures. The influence of annealing temperature on the phase-structural state of the alloys, hardness, and mechanical properties during tensile tests at room temperature and 650 degrees C has been studied experimentally. In cast condition and after deforming and annealing at 700...900 degrees C the alloy has a single-phase state with bcc lattice. In the annealing state alloy has a high value of strength characteristics and the elongation to fracture.
