摘　　要：采用非自耗真空电弧炉制备了不同组分的NiMnFeGaCex(x=0,0.6,1)合金铸锭。X射线衍射分析结果表明铸态合金主要为A2相,基体中有少量L12、D03相生成。铸态Ni10Mn5Fe60Ga20Al6Ce1合金磁致应变曲线有较好线性度,这对合金在微传感器和微驱动器中的实际应用有重要意义。The non-consumable vacuum arc prepared NiMnFeGaCexdifferent components(x = 0,0.6,1)alloy ingot.X-ray diffraction analysis shows that the alloy was cast as A2 phase,a small amount of the matrix L12,D03phase formation.Ni10Mn5Fe60Ga20Al6Ce1cast alloy magneto-strain curve has good linearity,which has important implications for the practical application of the alloy in micro sensors and micro drive.
