摘　　要：系统研究了Mn和Cr元素掺杂对Ni_(55)Fe_(18)Ga_(27)合金马氏体相变温度和居里温度的影响.研究表明:随着Mn含量的增加,Ni_(55-x)Mn_xFe_(18)Ga_(27)系列合金的马氏体相变温度逐渐降低,居里温度有所增加;Ni_(55)Fe_(18-x)Mn_xGa_(27)系列合金的马氏体相变温度也逐渐降低,但居里温度变化并不明显.随着Cr含量的增加,Ni_(55-x)Cr_xFe_(18)Ga_(27)系列合金的马氏体相变温度明显降低,居里温度则小幅度降低;Ni_(55)Fe_(18-x)Cr_xGa_(27)系列合金的马氏体相变温度和居里温度均有规律的降低.The influences of Mn and Cr doping on the martensitic transformation temperature and Curie tempera- ture of Ni55Fel8Ga27 alloy have been systematically studied in this paper. The results demonstrate that the marten- sitie transformation temperature reduces gradually and Curie temperature increases with the increasing Mn content in Ni55-xMnxFels Ga27 alloys. For Ni55 Fe18-xMnx Ga27, the martensitic transformation temperature also reduces and Curie temperature is basically similar. With the increasing Cr content in Ni55-xCrxFe18Ga27 alloys, the mar- tensitic transformation temperature decreases significantly and Curie temperature deereases slightly. For Nis5 Fe18-xCrxGa27 alloys, the martensitic transformation temperature and Curie temperature decrease simultaneously.
