Thermal Cyclic Characteristics under Load in a Ti<sub>50.6</sub>Pd<sub>30</sub>Ni<sub>19.4</sub> Alloy

Abstract

The thermal cyclic characteristics under load were investigated in a Ti 50.6 Pd 30 Ni 19.4 alloy. It is shown that the M s temperature, transformation strain and total plastic strain increase with increasing the number of the cycles and the increments increase with an increase of applied stress. All the above changes due to thermal cycling under load occur rapidly in the early cycles and then remain constant after a sufficiently large number of cycles. Thus, the cyclic training is effective to stabilize the martensitic transformation and shape memory characteristics of the alloy.
