摘要
The microstructure and mechanical properties of AlCuMgAg doped with Ce and Ti were investigated by tensile testing and microstructure analysis. It is shown that Cc and Ti doping increases the hardness and improves the tensile strength. Moreover, the Ce doping can improve the heat resistance of the alloy. By microstructure analysis, it is shown that the kinds of the precipitation-strengthening phases are not changed, although they decrease in size and increase in density. When both Ce and Ti were doped into the AlCuMgAg alloy, a new AlTiCeCu compound that is harder and brittle is formed, the precipitated phases were inhibited, and the tensile strength of the alloy decreased.
