ABSTRACT
The multilayer sample based on titanium alloy of the Ti-Zr-Nb system was obtained by the WAAM (TIG method) with filler metal-powder wire, the basis of which is powder obtained by the Hydrogenation-DeHydrogenation method. As a result, a 9-layer sample was produced. Its microhardness is at the level of 4200-5000 MPa. The effect of various types of heat treatment (vacuum annealing, quenching, quenching with aging) on the microstructure and microhardness of the obtained metal was studied.
