The dispersoid distribution of the second phase could strengthen the surface of the alloy, which decreased the quantity of abrasive particles. The wear volume of the alloy was decreased. The hardness and strength of the alloy were increased after ECAE. The resistance of deformation was improved and the depth and width of furrows were decreased due to the increase of hardness and strength. As a result, the wear-resistance and tribological properties of the alloy were improved after ECAE.

The results show t hat yttrium exists as the form of compound (Al2Y) in AZ31 magnesium alloy, and dystectic Al2Y as the heteromorphic nucleation emerges firstly in the cou rse of alloy precipitation, which refines the alloy's microstructure and obviou sly improves the mechanical properties at room and high temperature. The average grain size of AZ31 magnesium alloy containing Y is reduced by 35.82%. Tensile s trength, yield strength and elongation percentage reach 212 MPa, 147 MPa, and 7. 5% at room temperature respectively, and 117 MPa, 98 MPa, and 10.2% at 200 ℃ re spectively.

结果表明，Y在AZ31 镁合金中主要以块状Al2Y化合物形式存在；高熔点的Al2Y在合金凝固过程中首先析出，成为凝固的异质形核剂，从而细化了合金组织，改善了室温和高温力学性能；由于Y的强化，含Y AZ31镁合金平均晶粒尺寸降低幅度约为35.82 %；室温抗拉强度、屈服强度和延伸率分别为 212 MPa， 147 MPa和7.5%，200 ℃时分别为117 MPa， 98 MPa和10.2%。

This means that the residual strain in rolled alloy promoted the aging process. The influence of aging temperature on the room-temperature mechanical properties of 1〓, 2〓 and 6〓 alloys was tested and the results show that the 1〓 alloy without minor element additive is very sensitive to the aging temperature. Over-aging occurred easily when the aging temperature is somewhat higher, so it is difficult to control the aging treatment in production. The 6〓 alloy with combined Mg, Cr, Co additives showed less tendency of over-aging, the alloy can be aged in a wider temperature range and the mechanical property is stable. So the treatment process can be easily controlled.

对不同微量添加元素的1〓、2〓和6〓三种合金经热轧态时效后的室温力学性能表明，不添加微量元素的1〓合金对时效温度较敏感，温度偏高时容易产生过时效，且过时效的温度明显低于加Mg的2〓合金和同时加Mg、Cr、Co的6〓合金，这对生产过程中的工艺控制增加了难度，6〓合金的过时效倾向最小，合金可以在较宽的温度范围内进行时效，力学性能较稳定，使生产工艺较易控制。

The present Cu-20Ni-25Co alloy forms a continuous of Co2O3 layers over the surface of alloy because Cu-20Ni-25Co alloy formed by adding Ni to Cu-Co alloy decrease the critical concentration of forming reactive component oxides.
