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粗二次相的改性。此外，改性效果也改变了二次相的分布均匀性。SN - 0161-0457 UR - https://doi.org/10.1155/2018/3472743 DO - 10.1155/2018/3472743 JF -扫描PB - Hindawi KW - ER -
