Abstract:
A process for making a work piece having a major phase of &agr;â€³ from a titanium alloy comprising the following steps:quenching a work piece having a temperature higher than 800Â° C. to a temperature lower than 500Â° C. at a cooling rate greater than 10Â°C./second between 800-500Â° C., so that the cooled work piece contains &agr;â€³ phase as a major phase, wherein said work piece is made of a titanium alloy selected from the group consisting from the following a), and b): a) a titanium-molybdenum (Tiâ€”Mo) alloy consisting essentially of 6-9 wt % of Mo, and the balance titanium; b) a titanium-niobium (Tiâ€”Nb) alloy consisting essentially of 10-30 wt % of Nb, and the balance titanium.
