Abstract
Nickel/titanium alloys containing less than a stoichiometric quantity of titanium, which have a high austenitic yield strength and are capable of developing the property of shape memory at a temperature above 0.degree. C., may be stabilized by the addition of from 7.5 to 14 atomic percent copper. These stabilized alloys also possess improved workability and machinability.
