| Abstract: | The effect of heat treatment on bending-fatigue property of the 50.6at% Ni-Ti alloy wire has been studied in this paper. The results show that the wire has different bending-fatigue life after solution treatment and aging; the wire that solution treated at 1023k and aged at 673k has the longest life; the tensile strength has the same trend as bending-fatigue life,deformation and aging are helpful to increase the bending-tatigue property; the oxidation surface decrease the bending-fatigue property obviously, which have been discussed preliminarily. |
