Abstract
A method of treating a component formed from a Ni--Ti based shape memory alloy, so that the component exhibits superelasticity, comprises cold working the component, annealing the alloy while the component is restrained in the configuration resulting from the cold working step, and exposing the component to a temperature that is less than the solvus temperature of the alloy and greater than the temperature to which it is exposed in the annealing step to cause the A.sub.f temperature to be reduced.
