稀土的开发和综合利用已成为材料科学的重要课题,而相图是材料科学的基础。测定Al-Sb-Yb三元系室温相图,将对该系合金材料的发展,扩大锑、铝的应用和改善铝合金的性能是有益的。Al-Sb二元系有一个同成分熔化的计量化合物AlSb(图la),Al-Yb二元系存在两个中间相Al_2Yb和Al_3Yb,均为计量化合物(图1b),Sb-Yb二元系存在 The development and comprehensive utilization of rare earth has become an important issue of material science, and phase diagram is the basis of material science. Determination of Al-Sb-Yb ternary room temperature phase diagram will be beneficial for the development of the Department of alloy materials, expand the application of antimony and aluminum and improve the performance of aluminum alloy. Al-Sb binary system has a melting composition of the same compound AlSb (Figure la), Al-Yb binary system there are two mesophases Al 2 Yb and Al 3 Yb, are metered compounds (Figure 1b), Sb-Yb binary system exist
