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 transformationstart 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 inthe range of 620 to 640 K.This seems to be related to the minimum recoverable strain energyemerged from the above mentioned temperature range.
