Mechanical Properties and High-Temperature Stability of Ti-Mo-Al Alloys.

Abstract

The phase diagram of the isopleth section of the TI-7 at % Mo-Al system has been improved and expanded to include alloys up to 25 at % aluminum. The mechanical and thermal stability of alloys aged in the two-phase region, beta + Ti3Al, and in the three-phase region, beta + alpha + Ti3,Al, were correlated to the microstructures. Considerable increases in high-temperature strength and ductility, as well as high-temperature stability, were achieved in a Ti-7 at % Mo-16 at % Al alloy by step-aging. (Modified author abstract)
