Abstract
The article presents the results of studies of the mechanical properties of the titanium alloy Ti4.25Al-2V, fabricated by direct metal deposition on equipment developed by State Marine Technical University. A comparative analysis of the mechanical properties of the deposited metal in comparison with cast and forged metal is carried out. It is shown that the high level of its properties as regards cast metal is associated with differences in its structure, in particular, with high dispersion
