BASIC DIRECTIONS OF THE DEVELOPMENT OF TITANIUM-ALLOYS FOR MODERN ENGINEERING

Titanium metallurgy is being intensely developed at the present time, especially in foreign countries. A great number of titanium alloys oft en repeat each other in their physical and mechanical properties. Each country (Russia, the U.S., Great Britain, France, and in recent years , China and Japan) creates its own ranges of industrial titanium alloy s that often differ only in the combination of alloying elements rathe r than in the set of their properties. The present paper is an attempt to determine the main directions of advancements in titanium alloys w hich, in the opinion of the author, are of great interest for modern e ngineering.
