Ultrasonic Surface Treatment of Titanium Alloys. The Submicrocrystalline State

The paper presents the results of the research on improvement of physical-and mechanical properties of titanium alloys VT1-0 and VT6 by modification of surfaces using ultrasonic treatment, and a comprehensive study of the microstructure and mechanical properties of modified surface layers. It has been established that exposure to ultrasonic treatment leads to formation in the surface layer of a structure with an average size of elements 50 x100 nm, depending on the brand of titanium alloy
