Microstructure and Mechanical Properties of Mg-Y-Sm-Ca Alloys

Abstract:

The microstructure and mechanical properties of as-cast Mg-5Y-(2, 3, 4)Sm-0.8Ca (wt.%) alloys have been investigated. The results show that the microstructure of as-cast alloys consists of α-Mg matrix, Mg₂₄Y₅, Mg₄₁Sm₅ and Mg₂Ca. With the increase of Sm addition, the tensile strength increases at first, and then decreases. Mg-5Y-3Sm-0.8Ca alloy has the highest strength and can be a basis for developing light structural materials.
