摘要： A method of forming a sintered nickel-titanium-rare earth (Ni—Ti-RE) alloy includes adding one or more powders comprising Ni, Ti, and a rare earth constituent to a powder consolidation unit comprising an electrically conductive die and punch connectable to a power supply. The one or more powders are heated at a ramp rate of about 35° C./min or less to a sintering temperature, and pressure is applied to the powders at the sintering temperature, thereby forming a sintered Ni—Ti-RE alloy.
