本文借助于x射线粉末衍射法、金相观察和化学分析法研究了Al-Mg-Sm三元合金相图的400℃等温截面,它包括15个单相区、27个二相区和13个三相区,未发现三元金属间化合物。
Phase equilibria in Al-Mg-Sm system at 400℃ have been investigated by means of microstrueture and chemical analysis as well as X-ray powder diffraction techniques. 15 single-phase regions, 27 two-phase regions and 13 threephase regions were found in this system. The microstructural observations show that the solubilities of Sm in Mg_5Al_8 and Mg_(17)Al_(12) are less than 0.5 and 1.0 wt-％ respectively. No evidence of new phase has been observed in the system.
