Abstract
A method of producing homogeneous nickel-titanium base shape change memory lloys which includes the following steps in order: PA1 (1) converting a conventionally prepared nickel-titanium base shape change memory alloy into particles which are in the form of powder, shot, chips, or flakes; PA1 (2) blending or mixing the nickel-titanium base alloy particles; PA1 (3) melting the nickel-titanium base alloy particles; and PA1 (4) allowing the molten nickel-titanium base alloy to solidify into a desired shape.
