摘要：

This article discusses test results of corrosion mechanical properties and fatigue properties of deformed semifinished items (forgings and pipes) made of titanium alloys PT-7M and PT-7M with addition of ruthenium. The main mechanical properties of titanium alloys, the structure, and the ruthenium distribution in the structure are determined. Results of static three-point bending tests of specimens with crack are discussed for determination of corrosion mechanical strength and cyclic fatigue strength of forgings and pipes of these alloys in a corrosive medium. © 2017, Pleiades Publishing, Ltd.
