Abstract
The microstructure and corrosion properties of an as-cast Mg-4Al-2Sn alloy with different levels of Sr content (0, 1, 2 wt%) were investigated. A new rod-like MgSnSr ternary phase was identified in the alloys containing Sr. The grain size decreased with an increasing Sr content. The corrosion properties were improved by increasing the Sr content. The improved corrosion properties of the Mg-4Al-2Sn-Sr alloys is related to MgSnSr phase and grain refinement. The uniformly dispersed MgSnSr phase within the grain and grain boundary perform the role of an effective barrier for retarding corrosion propagation.
Key Words
