Abstract
Calculated CCD-diagram (continuous-cooling-transformation diagram) was derived for titanium alloy of Ti–Al–Zr– Si–Mo–Nb–Sn system to determine the phase transformation kinetics. The structures and microhardness of samples of heat-resistant titanium alloy of Ti–Al–Zr–Si–Mo–Nb–Sn system, quenched from different temperatures, were studied. It was proved that application of computational methods of modeling the structure-phase transformations for heat-resistant titanium alloys allows obtaining results close to the experimental values. 11 Ref., 1 Tabl., 5 Fig.
Keywords: heat-resistant titanium alloy, thermodynamic modeling, phase transformation, deformation processing, temperature, structure, phase, microhardness
