THE PRODUCTION OF EQUIPMENT V. A. Besednyi and S. N. Lotsmanov UDC 621.791.3:546.281 Type AT3 titanium alloy is included in the type AT six-component (Ti -At- Cr -Fe- Si -B) series of alloys containing variable quantities (3-8%) of aluminum with a constant total quantity of/3-stabilizing elements (Fe, Cr, Si, and B) within the limits of 1-1.8%. The structure of AT3 alloy is a single-phase solid solution with the stabilizers contained in the aIloy in quantities not exceeding their maximum solu- bility in a-titanium [1]. AT3 alloy is a medium strength alloy, welds quite well, and is worked by pressure [2]. The com- paratively large spread in the mechanical properties of the metal is a result of the fact that with certain deviations in the chemical composition of AT3 alloy or in the methods of working in the production of rolled products there is a breakdown in its single-phase nature with the formation of metastable ~-phase, intermetallides, or a'-phase.
