An experimental–theoretical technique is proposed to determine the thermophysical properties of titanium alloys in the liquid phase. This technique is based on analyzing the liquid bath profiles in fully solidified ingots after vacuum arc remelting (VAR). The experimental part of the technique makes it possible to easily estimate liquid bath contours without any markers, such as radioactive isotopes. The theoretical part is based on solving the inverse heat conduction problem for a solidifying ingot. The developed technique is used to determine some thermophysical parameters of the liquid bath and boundary conditions for VAR of titanium alloys Ti–6Al–4V, Ti–5Cr, and Ti–3Fe, since it is extremely difficult to measure them directly. © 2015, Pleiades Publishing, Ltd.
