A method of treating a component formed from a Ni-Ti based shape memory alloy, so that the component exhibits super-elasticity, 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 f temperature to be reduced.
