Abstract

PURPOSE: To manufacture a Ti alloy having superior strength and toughness by subjecting a Ti alloy to multistage working in which the working temp. in the succeeding stage is made lower than the working temp. in the preceding stage and rapid cooling is carried out every time a working stage is finished and by subjecting the worked Ti alloy to conventional heat treatment.
CONSTITUTION: When a superplastic Ti alloy material, a high strength and toughness forged or rolled Ti alloy article or the like is manufactured, a Ti alloy is subjected to multistage working. In the multistage working, the working temp. in the succeeding stage is made lower than the working temp. in the preceding stage, the final working temp. is made as low as possible, and rapid cooling is carried out every time a working stage is finished. The cooling rate is made as high as possible to make the grains fine and to increase the strength. The worked Ti alloy is subjected to conventional heat treatment by soln. heat treatment and aging to improve the toughness.
