Abstract
Calculated continuous-cooling-transformation diagram (CCT-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 alloying 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.
Keywords: heat-resistant titanium alloy, thermodynamic modeling, phase transformation, deformation processing, temperature, structure, phase, microhardness
