- Abstract
The grain refinement effect and related strengthening of alloying element Sb on as-cast Mg-5Y-3Sm-0.8Ca (wt.%) alloy were investigated by microstructure observation, theoretic calculation and tensile tests. The results showed that Mg3Sb2 phase with high melting point is formed in the alloy after Sb addition. Mg3Sb2 phase can become the effective heterogeneous nucleation core of -Mg matrix, and refine the grain size and improve the microstructure of the alloy. It causes the grain refinement strengthening and enhances the tensile strength of the alloy. When the content of Sb addition is 0.5%, the tensile strength of the alloy at room temperature is 234MPa. It can be a basis for developing light structural magnesium materials.
