摘要
采用普通铸造的方法,研究了不同冷却速度和磷含量对A lCuMn合金的显微组织及相组成的影响。研究发现:在合金中加入了磷后观察到有花瓣状组织和平行杆状组织出现,经过XRD分析,确定其为准晶相。另外,加磷以后,合金的布氏硬度下降,基体的显微硬度随磷含量的增加先降低后增大。
The effect of cooling rates and the amount of phosphor on as - cast structure of AlCuMn alloys by the common casting are studied. It is found there are much flower - like and parallel structure in AlCuMn alloys. In addition, the hardness of the alloys is decreased , which is ensured as quasicrystalline by XRD analyse, the microchardness of matrix falls at first ,and then increases.
