The elastic limit and 0.2% yield strength of nonlinear elastic materials were confirmed by cyclic loading-unloading tensile tests. The mechanical parameters of Ti- 23Nb- 0.7Ta- 2Zr- 1O,Ti-23Nb- 0.7Ta- 2Zr- 1.2O,Ti- 23Nb- 0.7Ta- 2Zr- 0.7O and Ti- 25Nb- 0.7Ta- 2Zr- 1.2O alloys were obtained by using this method. It is found that the elastic limit,yield strength and tensile strength of the alloys increase with the increase in contents of the additional elements. The elastic modulus of the alloys also increases with the plasticity deteriorating as the contents of the additional elements increase. The ratio of deformation has a significant effect on the improvement of elastic limit while slightly affects the yield strength and tensile strength of the alloys. The increase in the contents of elements and the ratio of deformation makes the tensile curve straight.
