Combined addition of Ti and Ce elements at the ratio of 1 : 3 resulted in the samples reaching maximum comprehensive tensile properties. In this case, the short needle-like phase was uniformly distributed in the microstructure. Few polyhedral phases could be found in the Al-Si-Cu-Fe-Mn matrix. The strengthening of these fabricated materials was due to the grain refinement for α过程和修改为粗二次阶段。此外,分布均匀性的第二阶段也改变了他们的改性效果。SN - 0161 - 0457 UR - https://doi.org/10.1155/2018/3472743 - 10.1155 / 2018/3472743摩根富林明扫描PB - Hindawi KW - ER
