Physicochemical Theory of Heat Resistance and New Heat-Resistant Titanium Alloys,
Abstract
An increase in the heat-resistance of titanium is explained by the formation of solid solutions and compounds with a varying degree of dispersity and chemical bond strength, i.e. a solution and dispersion mechanism for the hardening of liter - and beta - solid solutions and the formation of strong titanium compounds. Of particular importance for the heat-resistance of titanium systems are titanium compounds which are formed in them during crystallization, as well as from solid solutions, for example in Ti-Al, Ti-Cu, Ti-Si, Ti-Sn systems and many others. The regularities established for changes in heat resistance according to the composition and structure of binary and ternary titanium systems were used to investigate the heat resistance of more complex titanium systems and to establish the optimum compositions of new heat-resisting titanium systems. These investigations resulted in the development of compositions for new heat-resisting alloys of the ST series with operating temperatures above 600 degrees.
