Simulation of processes of high-temperature gas corrosion of titanium alloys in vacuum

A physicomathematical model of the process of high-temperature interaction of titanium alloys of the system Ti-Al-Mn in a rarefied medium has been considered that takes into account gas saturation of the metal and sublimation of the alloying element. The example of the alloy OT4-1 illustrates the fact that the model representations and the experimental data are in satisfactory agreement. The model representations can be apparently extended also to other types of alloys. The model can be used for expert estimation of the effect of a vacuum in the heat treatment or the utilization of titanium alloys.Translated from Fiziko-Khimicheskaya Mekhanika Materialov, Vol. 26, No. 6, pp. 29–34, November–December, 1990.
