Abstract

Effects of Y and Ce addition on microstructure and mechanical properties of squeezing casting Mg-6Al alloy were investigated by OM（optical microscope） and SEM（scanning electron microscope）,universal tensile tester.The results indicate that microstructure of squeezing casting Mg-6Al alloy is transformed from net-like structure into discontinuous net-like structure,in which the grain size is greatly refined,and mechanical properties of the alloy at room temperature can be significantly raised with Y and Ce mixed addition.Tensile strength and elongation of the squeezing casting Mg-6Al alloy with 0.5% Ce and 0.5% Y addition are increased from 126 MPa to 200 MPa and from 1% to 8.5%,respectively.

摘要

借助光学显微镜、扫描电镜和万能拉伸测试仪

对添加稀土Y和Ce的挤压铸造Mg-6Al合金的显微组织和力学性能进行了分析。结果表明

采用挤压铸造工艺

在复合添加稀土Y和Ce后

晶粒组织明显细化

显微组织由网状变为断网状

室温力学性能得到大幅度提高。添加0.5Ce和0.5Y时

挤压铸造Mg-6Al合金的抗拉强度从126MPa提高到了200MPa

伸长率从1.0提高到了8.5。

universal tensile tester.The results indicate that microstructure of squeezing casting Mg-6Al alloy is transformed from net-like structure into discontinuous net-like structure

in which the grain size is greatly refined

and mechanical properties of the alloy at room temperature can be significantly raised with Y and Ce mixed addition.Tensile strength and elongation of the squeezing casting Mg-6Al alloy with 0.5% Ce and 0.5% Y addition are increased from 126 MPa to 200 MPa and from 1% to 8.5%

respectively.
