Samples of products of domestic nonspherical powders of VT-20 titanium alloy were produced by the method of electron beam 3D fusion. Microstructure of deposited metal is pore-free, finely dispersed and uniform over the entire surface of the section. It is acicular a′-phase of titanium with a small content of b-phase. Sample microhardness is from HV 3960 to HV 4150 MPa. Uniform distribution of alloying elements and decreased content of aluminium due to its volatility in deposition was noted. Presence of insignificant porosity and increased roughness on part edges was detected. The methods of their elimination were obtained. 10 Ref., 1 Table , 11 Figures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
