Short-Term and Lasting Stability of Beta-Alloy Systems Ti-Mo-Cr-Fe-Al at High Temperatures (Kratkovremennaya i Dlitelnaya Prochnost Beta-Splava Sistemy Ti-Mo-Cr-Fe-Al pri Vysokikh Temperatorakh),

Abstract

The effects of various methods of heat processing of alloys as to heat resistance and mechanical properties were investigated. Tests showed that an alloy seasoned at 550C for 15 hours had the least deformation at high temperatures. These alloys had the best mechanical properties and can be used as heat-resistant material up to 450C. They retain stability in limits 130-127 kg (force)/sq mm, pliability 6-8%. It is possible to obtain highly heat-resistant properties in an alloy by selecting the proper thermal process to produce a polygon structure of the Beta-grain which in turn creates a uniform distribution of alpha-phase.
