采用金相显微镜（OM）、X-射线衍射仪（XRD）、差热扫描仪（DSC）等分析手段对Mg-15Ca-15Zn-6Cu合金相变储热材料的组织结构与热物性参数进行了分析。通过反复熔化-凝固热循环试验

研究了该合金的热循环稳定性。结果表明

Mg-15Ca-15Zn-6Cu合金经历1 000次热循环后的相变温度和相变潜热分别为510.2℃和198.7J/g

与循环前的初始合金相比

相变温度提高了5.5%

相变潜热减小了5.56%

因此

表现出良好的热循环稳定性。

The microstructure and thermo-physical properties of Mg-15Ca-15Zn-6Cu phase change heat storage alloy were investigated by optical microscope（OM）

X-ray diffraction（XRD）and differential thermal scanner（DSC）.By the experiment of melting/freezing thermal cycle

thermal cycling stability of the alloy was analyzed.The results show that

after 1 000 thermal cycles

the phase change temperature and phase change latent heat reach 510.2 ℃ and 198.7J/g

respectivly.Compared with the primary alloy

the phase transition temperature is increased by 5.5%

and phase change latent heat is decreased by5.56%

so the Mg-15Ca-15Zn-6Cu alloy exhibits satisfied thermal cycling stability.
