description: Additive manufacturing of titanium alloys is one of the most growing areas of 3D metal printing. Using of AM methods for parts production in the aviation industry is especially promising. During the deposition products with a different size cross section, the thermal history changes, which leads to non-uniform of the structure and properties. Such heterogeneity can lead to failure of the product during operation. The aim of the work is to develop methods of increasing the operational characteristics of direct laser deposited titanium alloy VT6 based on the principles of phase and structure state control. In the work the microstructure and properties of the initial powder material were studied. The regularities of formation of microstructure and phase composition of samples at change of linear energy, influence on quantity of metastable martensite phase Î±' are considered. The influence of additional scanning as well as different types of heat treatment on morphology and quantity of metastable martensite phase Î±' is studied. As a result of the work the requirements to the BT6 powder alloy for the DLD technology were formulated. The results of structural and phase studies of samples from titanium alloy after direct laser growing have been obtained, obtained on modes with different linear energy, with different types of laser beam scanning, as well as after thermal treatment. Calculated thermal cycles are obtained and compared with mechanical properties of products obtained by direct laser growing technology. The modes of thermal treatment of BT6 titanium alloy after direct laser deposition are developed.
