In order to assess the possibility of using magnesium alloys with high Al and Zn contents as degradable fracturing balls, the effects of Si addition on microstructures, mechanical properties and degradable behavior of Mg-17Al-5Zn (mass.%) alloy were investigated. The results show that the minor Si addition can refine α-Mg matrix and modify Mg2Si particles. With the increase of Si content, the yield...
