Elevated Temperature Mechanical Behavior of Mg-Y-Zn Alloys

Abstract:

Article Preview

The elevated temperature mechanical behavior of Mg-Y-Zn alloys was investigated. It was found that the extruded Mg-Y-Zn alloy exhibited excellent mechanical properties both at ambient temperature and elevated temperature. With the increase of tensile temperature, the ultimate tensile strengths of Mg-Y-Zn alloys decreased and their elongations increased. The ultimate tensile strengths increased and elongations decreased with the increase of yttrium content. However, a gradual increase in the ultimate tensile strength and elongation both at ambient temperature and elevated temperature was obtained by increasing both yttrium and zinc contents. The fracture modes of Mg-Y-Zn alloys at different tensile temperature were also investigated.
