Abstract: The dependence of high temperature shape memory effect on the pre-deformation tempera- ture of the Ti_(50)Ni_3Pd_(37) alloy has been studied.This alloy,of which the reverse transformation start temperature on heating is 620 K,has both one-way and two-way shape memory effects. The maximum shape memory strain of the ahoy may be obtained under pre-deformation in the range of 620 to 640 K.This seems to be related to the minimum recoverable strain energy emerged from the above mentioned temperature range.

Key words: Ti-Ni-Pd alloy, shape memory effect, shape memory strain, recoverable strain energy
