摘要:  A process for making an article of a titanium alloy having α″ phase as a major phase according to the present invention includes providing a work piece of a titanium alloy consisting essentially of 7-9 wt % of molybdenum and the balance titanium and having α″ phase as a major phase; and cold working at least a portion of the work piece at room temperature to obtain a green body of the article, wherein the cold worked portion of the green body has a thickness which is 20%-80% of that of the at least a portion of the work piece, and the cold worked portion has α″ phase as a major phase.
主权项:  A process for making an article of a titanium alloy having α″ phase as a major phase comprising the following steps: a) providing a work piece of a titanium-molybdenum alloy having α″ phase as a major phase; and b) cold working at least a portion of said work piece at room temperature once or repeatedly to obtain a green body of said article, wherein the resultant cold worked portion of said green body has an average thickness which is 10%-90% of an average thickness of before cold working said at least a portion of said work piece, and the cold worked portion has α″ phase as a major phase, wherein said cold working in step b) is either carried out once and the resultant cold worked portion of said green body has an average thickness which is 50%-90% of an average thickness of said at least a portion of said work piece; or said cold working in step b) is carried out repeatedly and each time of said repeated cold working results in a reduction of an average thickness of the cold worked portion being less than about 40% wherein the titanium-molybdenum alloy in step a) consists essentially of about 7.5 wt % of molybdenum and the balance titanium; and wherein said cold worked portion resulted from step b) has α″ phase as a major phase and α′ phase as a minor phase.
