| 摘 要： | 在实验基础上提出了铝合金熔体直接氧化形成的Al2O3／Al Lanxide复合材料中气孔的形成机理;考察了母合金中掺杂元素(Mg、Si)含量和工艺温度对Al2O3／Al Lanxide复合材料气孔率的影响规律．研究结果表明,当工艺温度升高时,Al2O3／Al Lanxide复合材料的气孔率降低;当母合金中的镁含量增加时,材料的气孔率上升;而母合金中的硅含量对材料的气孔率几乎无影响．

| Abstract: | This paper puts forward the mechanism of the gas h ole formation in the Al 2O 3/Al Lanxide composites formed by the direct oxidation of molten aluminum alloy based on the experiments. The effects of the processing temperature and the contents of doped elements Mg and Si in the parent alloy on the gas hole contents of Al 2O 3/Al Lanxide were also investigated. It is revealed that the gas hole contents in the Al 2O 3/Al Lanxide composites decrease with the increase in the processing temperaure and with the decrease in the Mg content in the parent alloy, and that the content of Si in the parent alloy has little effect on the gas hole contents. |
