摘要:
为改善电锤用镁合金曲轴箱件的服役性能,在重力铸造条件下,研究了RE对AM60B合金组织和性能的影响,得出AM60B合金中RE的最佳添加量；然后在工厂压铸条件下,根据重力铸造条件下得出的RE的最佳添加量向AM60B合金中加入RE,研究加入RE前后对压铸件组织和性能的影响.结果表明,重力铸造下,AM60B合金中RE的最佳添加量为1.0％；当添加1.0％的RE后,AM60B镁合金曲轴箱件的显微组织细化,B相的变质良好,晶粒尺寸由原来的39μm细化到20 μm；并且压铸件的硬度、冲击韧性和台架耐久性能都得到提高.
Abstract:
To improve the service performance of magnesium alloy crankcase used in the electric hammer,theeffect of RE on the microstructures and properties of AM60B alloy is studied ,and the optimum content of REin AM60B alloy under the gravity casting condition is obtained. Then the RE is added into the AM60B alloyunder the industrial die casting condition,and the effect of RE on the microstructures and properties of die -castings is studied. The results show that the optimum content of RE is 1.0% under the condition of gravitycasting. When 1% RE is added into the AM60B magnesium alloy crankcase,the microstructures are refinedand the average grain size decreases from 39um to20pum. The brinell hardness,impact toughness and benchendurance property of the crankcase are all improved.
