英文摘要Rare earth (RE) elements Er and Zr both of 0.05, 0.15 and 0.25 wt% were added to ZL205A alloy. The effect of trace RE addition on the microstructure and properties of as-cast and T5 heat-treated alloys was investigated. The results show that trace Er and Zr elements can effectively improve the fluidity of the alloy, refine the grains and promote the 0 phase to concentrate on the intersection of the grain boundaries. When their addition amount is 0.15 wt%, the mechanical properties of as-cast alloy decline greatly compared with those of the initial alloy; after T5 heat-treatment, the tensile strength, the Vickers hardness and the elongation reach 358 MPa, 1070 MPa and 2%, respectively, when the comprehensive performance is the best. T5 heat-treatment can make the microstructure and composition uniform, and also lead solute atoms to diffuse sufficiently. Therefore, it hinders the dislocation movement and sub-boundary migration during the deformation process, taking an adverse impact on the elongation.
