摘要：

The effect of single addition of La or Sm on the microstructures and mechanical properties of an Al-Cu-Mn alloy were investigated by microstructure characterization and tensile test.The results show that addition of La or Sm into the Al-Cu-Mn alloy can remarkably increase the density of θ' phase and refine the microstructure,and thus,improves the mechanical properties at room temperature.La addition results in a more considerable increase in the density and refinement of θ' phase than Sm addition.La addition has a more significant contribution on the mechanical properties of the Al-Cu-Mn alloy than Sm addition.In addition,a new phase of Al6Cu6La is formed in the Al-Cu-Mn alloy with La addition.
