The paper presents the results of structure and texture formation study in Ti-6Al-4V alloy samples, obtained by Direct Metal Deposition technology of additive manufacturing. The effect of annealing on the formation of the structure and texture in 3D-samples was investigated. It is shown that the samples have a two-phase structure of “basket weaving” in the initial state and after annealing. It is established that the samples have significant anisotropy of properties in two mutually perpendicular directions that could be explained by the presence of the crystallographic texture.

The effect of the reference voltage on the texture in TiN, ZrN, Nb, Ta and W coatings obtained by PVD methods was investigated by X-ray method. It is shown that an increase in the reference voltage leads to an increase in the {111} texture to a weakening of this texture in W coatings. The results were interpreted on the basis of the features of elastic anisotropy in the material of coatings with a cubic lattice.

Al-Li alloys are considered. A quantitative approach to the determination of the ratio of the frac tions of the binary and ternary intermetallic phases in Al-Mg(Cu)-Li alloys is developed on the basis of chemical and phase composition balance equations and the experimentally measured lattice parameter of the α solid solution. The ratio of the fractions of the δ'(Al 3 Li) and S 1 (T 1 ) phases in Al-Mg(Cu)-Li alloys is shown to be determined by the ratio of the mole fractions of Li and Mg(Cu). Equations are proposed for cal culating the weight fractions of the S 1 (Al 2 MgLi), T 1 (Al 2 CuLi) and δ'(Al 3 Li) phases in domestic and foreign
