  "abstract": "In this study, the synergistic influence of Er alloying and heat treatment on the as-cast Mg-5Sm-0.2Ni alloy were comprehensively investigated. The results show that Er addition promotes the formation of a Mg(Er,Sm)₃ phase during the solidification process, and subsequent heat treatment alters the morphology, distribution and volume fraction of the Ni-containing LPSO phases, meanwhile promoting the precipitation of noodle-like Mg3Sm phases from an α-Mg matrix. Compared to the as-cast Mg-5Sm-0.2Ni alloy, the yield strength of the Mg-5Sm-1Er-0.2Ni alloy subjected to heat treatment increased from 88 ± 4 MPa to 144 ± 5 MPa, and the corrosion rate decreased from 492.6 ± 14.2 mm/year to 166.2 ± 12.4 mm/year. The enhanced yield strength of the heat-treated Mg-5Sm-1Er-0.2Ni alloy mainly originates from the finely dispersed Mg(Er,Sm)₃ phases and the noodle-like Mg₃Sm precipitates, while the reduced corrosion rate is due to the decreased volume fraction and coarsened size of the LPSO phases, which weaken the galvanic corrosion effect. This study provides a new approach for the preparation of Mg-Sm-Er-Ni alloys with high yield strengths and controlled corrosion rates.",
