ABSTRACT:
Nickel/titanium alloys containing less than a stoichiometric quantity of titanium, which are capable of having the property of heat recoverability imparted thereto at a temperature above the boiling point of liquid nitrogen, may be stabilized by the addition of from 1.5 to 9 atomic percent copper. These stabilized alloys also possess improved workability and machinability.
