Abstract
A method of treating a sample of an alloy which is capable of transforming between martensitic and austenitic phases, to render the alloy pseudoelastic, the method comprising: PA0 (a) annealing the alloy at a temperature which is greater than the stress relaxation temperature (T.sub.SR) of the alloy and less than the temperature at which the alloy is fully recrystallized (T.sub.x); and PA0 (b) deforming the sample at a temperature which is greater than about the maximum temperature at which the alloy can be made to transform from its austenitic phase to its martensitic phase by the application of stress (M.sub.d), and less than the stress relaxation temperature.
