Effect of heat input on structure and mechanical properties of an electron beam additively manufactured Ti–6Al–4V alloy
Working out of technological recommendations for modern additive manufacturing of titanium alloys is an important scientific and technical task for modern industry. The paper presents results of experimental studying the effect of heat input during wire and electron beam additive manufacturing (WEBAM) on the structural-phase composition and mechanical properties of a WEBAM-built Ti–6Al–4V alloy. Characteristic morphological and structural features of the as-built metal have been established. The as-built metal was represented by α‑Ti (HCP) and β‑Ti (BCC) lath structures. It has been shown that an increase in the heat input contributes to a higher ductility of the as-built metal with lower strength and microhardness values.
期刊介绍：
Russian Physics Journal covers the broad spectrum of specialized research in applied physics, with emphasis on work with practical applications in solid-state physics, optics, and magnetism. Particularly interesting results are reported in connection with: electroluminescence and crystal phospors; semiconductors; phase transformations in solids; superconductivity; properties of thin films; and magnetomechanical phenomena.
