Abstract
mathematical model of the process of dissolution of oxygen-containing inclusions of titanium in titanium alloy melt was constructed, which allows calculation of the dependence of particle dissolution rate on melt temperature. The dynamics of oxygen distribution in α-titanium particles during the dissolution process was established. Time intervals of complete dissolution of oxygen-containing titanium inclusions of different chemical composition and initial dimensions were determined. Ref. 20, Fig. 6.
Keywords: titanium; titanium dioxide; diffusion; dissolution; mathematical modeling
