The results of the experiment and numerical simulation of Ti-Al intermetallic compound synthesis using cold gas-dynamic spraying and heat postprocessing in an oven at a temperature above the aluminum melting temperature are presented. Ti-Al-type intermetallic systems were obtained at heating temperatures from 930 to 1620 K and phase composition and crystal structure of the compounds were studied. Numerical simulation of the intermetallic synthesis process performed by the molecular dynamics method had shown that the kinetics of the process at these temperatures is determined by the diffusion and dissolution processes of titanium in molten aluminum.
