系统研究了Ａｌ／ＣｕＯ的高能球磨固态反应。对Ａｌ含量在２０％～８５％范围内的Ａｌ／ＣｕＯ进行高能球磨，采用Ｘ射线衍射进行物相分析，并对Ａｌ含量分别为２０％和７５％的试验分析了物相随研磨时间的变化，做了差示扫描量热（ＤＳＣ）分析，对比研究了固态还原反应与固态复合反应过程的异同。结果表明，Ａｌ含量不超过２０％时仅发生单纯的还原反应；当Ａｌ含量从２０％分别增加到３５％，５７％，７０％和８５％时，反应为还原与合成共存的复合反应，产物依次为Ｃｕ９Ａｌ４，ＣｕＡｌ２及Ａｌ（Ｃｕ）固溶体和Ａｌ２Ｏ３的复合颗粒。
The high energy ball milling solid state reaction of Al / CuO was systematically studied. High-energy ball milling of Al / CuO with Al content in the range of 20% -85% was carried out. Phase analysis was carried out by X-ray diffraction. The change of phase with grinding time was analyzed for the Al content of 20% and 75% , A differential scanning calorimetry (DSC) analysis was done to compare the similarities and differences between the solid state reduction reaction and the solid state composite reaction process. The results showed that only a simple reduction reaction occurred when Al content did not exceed 20%. When Al content increased from 20% to 35%, 57%, 70% and 85% respectively, the reaction was a composite reaction of reduction and synthesis. Followed by Cu9Al4, CuAl2 and Al (Cu) solid solution and Al2O3 composite particles.
