Patent ID: 7083687

Claim:
A method for making a super-elastic titanium alloy for medical use comprising the steps of: preparing a titanium alloy ingot which consists essentially of: molybdenum (Mo) as a β stabilizer element of titanium (Ti) :from 2 to 12 at %; gallium (Ga) as an α stabilizer element of the titanium (Ti) :from 0.1 to 14 at %; and the balance being titanium (Ti) and inevitable impurities, subjecting the ingot to a homogenized heat treatment in a vacuum environment or an inert gas environment at a temperature ranging from 1,000 degree C. to 1,200 degree C., and cooling the ingot quickly to a room temperature; after cooling the ingot to the room temperature, cold working the ingot to prepare a sheet; and subjecting the sheet to a solution heat treatment in the vacuum environment or the inert gas environment at a temperature ranging from 600 degree C. to 1,100 degree C.
