摘要

Influence of the time and temperature of Ti–4Al–3V titanium alloy annealing after printing of samples by the wire electron beam additive technology (WEBAM) is investigated. It is shown that after treatment, the annealing at temperatures up to 850 °C predominantly increases the material plasticity with increasing fraction of the alpha-phase and almost full absence of the beta-phase. The content of the beta-phase increases, the plasticity decreases, and the material strength considerably increases after treatment at temperatures of 950 and 1050 °C. The increased annealing time at a temperature of 850 °C leads to the increase of the plasticity, and at temperatures of 950 and 1050 °C, of the material strength.
