By microstructure analysis and microhardness measuration, solid solution strengthening of Sm in Mg-10Y-1.5Sm alloy after solid solution and aging treatment was investigated. The results show that the microstructure of the alloy consists of α-Mg matrix and Mg24Y5 phase, and fine Mg24Y5 particles distribute in α-Mg matrix uniformly and dispersedly. No new phase forms after Sm addition, and Sm enhances α-Mg matrix and Mg24Y5 phase by solid solution effect. Compared with that of Mg-10Y alloy, the microhardness of the alloy with Sm addition increases obviously from HV87.7 to HV98.5.
