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
