description: Features of formation of an equilibrium Î±+Î² structure in a two-phase VT6 alloy after direct laser deposition with subsequent heat treatment. his work is devoted to the study of the influence of temperature and annealing time on samples obtained by direct laser growth on macro-and microstructure, microhardness, strength and ductility. The research set the following goals: The goals of the work include the study of world resear cheson the heat treat-ment of titanium alloys; selection of modes for heat treatment; study of macro-and microstructure of samples after annealing and their mechanical properties. Based on the results of the study, choose a mode that allows you to get the best mechanical characteristics. In addition, one of the tasks is to study the effect of heat treatment without vacuum on the oxidation of images.As a result,the samples were annealed at an exposure temperature from 600 Â° Ð¡ to 1050 Â° Ð¡ and an annealing timeof 1, 2, and 4 hours. The influence of temperature and time on the development and growth of new grains, the formationand growth of secondary phases, the thickness of the Î±-plate, and the change in the microstructure are studied. The mechanical properties of the samples, such as microhardness, strength, and ductility, were studied. The depth and microhardness of the alpha layer formed in the samples at temperatures from 750 Â°C were measured. Alpha layer is within the roughness of the surface of samples, obtained by direct laser deposition.As a result of the final qualification work, the recommended modes are: 850 Â°C, 4 hours; 900Â° C 1-2 hours.To relieve the residual stresses after growing the part is recommended pre-heattreatment consisting of annealing at 600 Â° C and holding for 2 hours
