It is also possible to induce a phase transformation
by applying a pure mechanical load. The result of this load application
is fully detwinned martensite and very large strains are observed.
If the temperature of the material is above A0f,
a complete shape recovery is observed upon unloading, thus, the
material behavior resembles elasticity. Thus the above-described
effect is known under the name of Pseudoelastic Effect.
A loading path demonstrating the pseudoelastic effect is schematically
shown in Figure 5, while the resulting stress-strain diagram
is shown in Figure 6.
