Abstract

Ti–6Al–4V alloy has been subjected to direct current heat treatments at 850, 900, and 950 °C, respectively. The results indicate that the α-phase coarsening could be effectively prevented by the high Joule heating rate and the short hold time. In addition, the tensile residual stress became a compressive stress, which increased with an increased hold time. A high hardness was obtained due to phase strengthening and the release of tensile stress.
