摘　　要：使用DSC分析Co79.5Sn20.5合金在降温过程中的热量变化,并使用自主设计的等效磁导率测量仪测量此合金在降温过程中等效磁导率的变化情况。当Co79.5Sn20.5合金发生结构变化时,其热量和等效磁导率都存在明显的突变。研究Co79.5Sn20.5合金在固态的无序-有序相变过程中结构及等效磁导率的变化,比较不同物理性质对合金结构变化的表征情况的结果表明,合金等效磁导率的变化可以表征其液-固相变、居里转变以及固态相变等结构转变。Thermal variation of the Co79.5Sn20.5 alloy during the cooling process was analyzed by the differential scanning calorimeter （DSC） and its equivalent magnetic susceptibility change during the process was measured using a new device. The magnetic susceptibility and the heat of the alloy will change abruptly when there are structure changes. During the disorder-order phase transition in the solid state the structure and the equivalent magnetic susceptibility were studied. Moreover, the comparison among the microstructure changes by different physical properties indicates that the solid-liquid transition, the Curie transition and the disorder-order solid transformation can be well characterized by the variations of the equivalent magnetic susceptibility
