    Microstructure and Mechanical Properties of AM60 Magnesium Alloy Sheet Processed by Equal Channel Angular Rolling

      摘要
    • 摘要: 采用等径角轧制工艺制备了AM60镁合金板材,并对轧制前后板材的显微组织与力学性能进行了对比.结果表明:经过等径角轧制后,板材晶粒取向由轧制前的(0002)基面取向演化为非基面取向,晶粒细化并有大量细密孪晶出现;板材强度明显提高,抗拉强度由轧制前的222 MPa增大到372 MPa,屈服强度由156 MPa增大到260 MPa,断后伸长率略有增加.

       

      Abstract: AM60 magnesium alloy sheets were prepared by equal channel angular rolling (ECAR),the microstructure and mechanical properties were examined.It was found that the orientation of the sheet processed by ECAR was changed and the crystal orientation evolved from (0002) basal plane orientation to non-basal plane.Compared with as-received sheet,the grain size decreased and refined twins were presented.The strength of the sheets after ECAR was enhanced obviously,the ultimate tensile strength increased from 222 to 372 MPa and the yield strength increased from 156 to 260 MPa.The elongation increased slightly.
