研究了塑性变形对γ─ＦｅＭｎＡｌＣｒ反铁磁合金电学性能的影响．结果表明，随形变量增加，γ─ＦｅＭｎＡｌＣｒ合金的室温电阻率和剩余电阻率先下降，后增加，在形变量４．８９％处存在电阻率的极小．合金在Ｎｅｅｌ温度（ＴＮ）以上的平均电阻温度系数（ＴＣＲ）随形变而增加，在ＴＮ和电阻极小值温度（Ｔｍｉｎ）之间ＴＣＲ变化不大，而在Ｔｍｉｎ～室温之间ＴＣＲ有明显减小．试验还发现塑性变形对γ─ＦｅＭｎＡｌＣｒ合金的应力灵敏系数影响不大．试验结果表明，γ─ＦｅＭｎＡｌＣｒ合金可能存在某种程度的成分偏聚．
The effect of plastic deformation on the electrical properties of γ-FeMnAlCr antiferromagnetic alloy was studied. The results show that the room temperature resistivity and the residual resistivity of γ-FeMnAlCr alloy decrease first and then increase with the increase of deformation, and there is a very small resistivity at the deformation of 4.89%. The average temperature coefficient of resistance (TCR) of the alloy above Neel temperature (TN) increased with deformation, and the TCR did not change much between TN and the minimum temperature of resistance (Tmin), while TCR decreased significantly from Tmin to room temperature small. The experiment also found that the plastic deformation of γ-FeMnAlCr alloy stress sensitivity factor has little effect. The experimental results show that γ-FeMnAlCr alloy may have some degree of component segregation.
