摘要：
Effects of ball-milling parameter on structures and properties of sintered Mg-1.5Zr(mass fraction,%) alloy were researched by metallographic analysis,mechanical properties tests and DMA technology.The results indicate that with 310 r/min rotation speed,the microstructure of the sintered alloy is greatly refined,and Zr-phase distributes uniformly.The micro-hardness,bending strength and damping capacities are the greatest under 310 r/min rotation speed.The damping peak of sintered Mg-1.5Zr alloy increases with increasing frequency under the testing conditions.The relaxation time meets the Arrhenius relationship,and shows the characteristics of relaxation damping.
