Abstract
A shape memory alloy including a Ni—Ti based alloy is superelastic at temperatures of about −40° C. to about 60° C. after being exposed to temperatures of about −55° C. to about 85° C. A method of forming a memory shape alloy may include preparing a rod comprising a Ni—Ti alloy, drawing a wire from the rod, and treating the wire at a temperature of about 500° C. to about 550° C. for about less than 1 minute.
