%X 通过铸锭冶金法制备了不同铜、锰合金元素含量的6013合金，研究了不同元素含量对合金微观组织和室温拉伸力学性能的影响。研究结果表明：Mn在铸锭均匀化过程中能细化晶粒，但过量的Mn使合金组织脆化；Cu元素质量分数由0.9%提高到1.1%时，合金的T6态抗拉强度由290 MPa提高到305.6 MPa，提高了7.3%，伸长率也有所提高，组织也得到有效改善。<br />
6013 alloys with different content of Cu and Mn alloy elements were prepared by ingot metallurgy. The results show that Mn can refine the grain in the process of ingot homogenization, but excessive Mn can embrittle the microstructure of the alloy. When the mass fraction of Cu element increased from 0.9% to 1.1%, the T6 tensile strength of the alloy increased from 290 MPa to 305.6 MPa, with an increase of 7.3%. The elongation and microstructure were also improved.
