چکیده انگلیسی
The microstructure and mechanical properties of AZ91 magnesium with Ca and Sb additives were investigated. Adding 2 wt% Ca refines the microstructure, reduces the amount of the Mg17Al12 phase significantly, and forms a new Al4Ca phase that is reticular in AZ91 magnesium; the tensile strength and elongation properties of the AZ91–2Ca alloys decrease at room temperature (RT). However, with the addition of Ca and Sb, the microstructure is further refined, and a new Ca2Sb phase is formed in AZ91 magnesium with a 0.1%–1.0 wt% Sb addition. Furthermore, the microstructure and mechanical properties of the alloys with the 0.4 wt% Sb addition are found to be optimum.
