EFFECT OF SILICON CONTENT ON THE STACKING FAULT ENERGY IN Fe-Mn-Si ALLOYS
Si 含量对 Fe-Mn-Si 合金层错能的影响

The intrinsic stacking fault energy of three Fe-Mn-Si alloys was calculated ac-cording to the thermodynamic model of stacking fault energy.The calculated results show thatthe stacking fault energy of Fe-Mn-Si alloys lowers with increasing Si content.The influence ofSi content on the shape memory effect in Fe-Mn-Si alloys was discussed on the basis of this.The shape memory effect enhances as the Si content increases in the specified range of Mn con-tent.
