Abstract

A method for the conversion of the thermodynamic characteristics of iron-based melts into those of titanium-based melts is used to calculate the change in the Gibbs free energy when oxygen dissolves in liquid titanium and when titanium is deoxidized by deoxidizing elements. It is established that beryllium is the most rational deoxidizer for structural, high-temperature, and functional titanium alloys and calcium is the most rational deoxidizer for foundry alloys. Free oxygen or volatile monoxides from liquid titanium cannot pass to a gaseous medium in vacuum, since it needs an unattainably low residual pressure.
