| Abstract: | To improve the mechanical properties of magnesium alloys,Sr as well as rare earth Y and Nd were introduced into AM60B.The chemical components and phase composition were analyzed using fluorescent X-ray and XRD.The influence of the additives on the mechanical properties of AM60B was studied.Also,the fracture surface of the specimens was investigated by SEM and the fracture behavior was discussed.The results showed that the mechanical properties of AM60B magnesium alloy were improved by the addition of Sr and rare earth elements Y and Nd.The highest values of the tensile strength and the elongation percentage reached 224.57 MPa and 9.25% respectively for AM60B magnesium alloy with the addition of Sr and Nd,which were enhanced 32% and 38% respectively than those of AM60B magnesium alloy.The yield strength of the alloy was also improved.Therefore,this alloy was optimized to be used for high temperature creep resistance test. |
