Abstract
Microstructure and mechanical properties of the hot-extruded Mg-1.5â¯at% Zn-2.0â¯at% Y-x at% Sn (xâ¯=â¯0, 0.5, 1.0, 2.0) alloys were investigated. The ultimate tensile strength (UTS), yield strength (YS) and micro-hardness of the alloys reached the peak values in the alloy with 0.5â¯at% Sn. The values of the UTS, YS and micro-hardness of the hot-extruded Mg-1.5â¯at% Zn-2.0â¯at% Y-0.5â¯at% Sn alloy were 379â¯MPa, 230â¯MPa, and 89.1 HV. It was found that the enhanced mechanical properties in the hot-extruded Mg-1.5â¯at% Zn-2.0â¯at% Y-0.5â¯at% Sn alloy were attributed to the precipitated MgZnY particles with nanoscale size and the uniformed distribution of the LPSO phase.
