| 摘 要： | 根据规则固溶体的热力学模型，分别计算铁锰硅、铁锰硅铬、铁锰硅铬镍形状记忆合金的层错能，研究硅、锰、铬、镍合金元素对铁基形状记忆合金层错能的影响。结果表明，锰、铬、镍元素均提高铁锰硅系合金层错能，而硅则降低合金的层错能，其中每１％（原子分数）元素变化对合金层错能影响比例，硅∶锰∶铬∶镍为：－０．２７∶１∶１．１∶１．７。为了获得较佳的形状记忆效应，加入铬、镍元素的同时，降低锰含量以使合金具有低的层错能

| Abstract: | The stacking fault energy of Fe-Mn-Si,Fe-Mn-Si-Cr and Fe-Mn-Si-Cr-Ni alloys respectively is calculated according to the thermodynamic model.The calculated results show that the stacking fault energy of Fe-Mn-Si system alloys decreases when Si% increases and the stacking fault energy of the alloys increases when Mn%,Cr% and Ni% increases.The effect ratio of alloy elements on stacking fault energy is -0.2711.11.7 ( Si%Mn%Cr%Ni% ).To obtain good SME,the stacking fault energy of alloys should be as low as possible.Manganese content decreases when adding chrome and nickel in order to low intrinsic stacking fault energy. |
