摘要

Ferromagnetic shape memory alloy is a kind of new smart material. Directional solidification method in producing polycrystalline Ni_2MnGa is mature and effective. In order to increase the strain of Ni_2MnGa polycrystalline prepared by directional solidification, mechanical training is an effective method. In this paper, the tests of temperature-induced strain are carried out in different directions of Ni_2MnGa prepared by directional solidification using three kinds of specimens with various mechanical training. Through analyzing the mechanical properties in different directions, the influence of mechanical training on the temperature-induced strain are investigated. Some conclusions which may provide references for the engineering applications of this material are gained.
