Abstract

The effect of minor Cerium addition on microstructure and ambient temperature mechanical properties of die-cast AM60 alloy was investigated in the text. The results show that new acicular phase Al₁₁Ce₃ is formed after that Ce is added to the AM60 alloy, α-Mg matrix phase morphology changes from dendritic crystal to equiaxed crystal gradually with the increase of Cerium content. The size and amount of Mg₁₇Al₁₂ (β) phase are decreased due to the Al₁₁Ce₃ formation, ambient temperature mechanical properties of die-cast AM60 alloy are greatly improved because of grain refinement.
