摘要
通过硬度、电阻测试,X射线衍射分析,以及光学显微镜、扫描电镜、透射电镜观察,研究了3003铝合金箔制备过程中的组织演变,探讨了Fe、Si杂质元素对3003铝合金组织及性能的影响。结果表明,随(Fe+Si)含量升高,Mn的固溶度降低,且αAl(Fe,Mn)Si相增多;3003铝合金冷轧后在300℃和500℃退火时有大量含Mn粒子析出,300℃退火时析出受到冷轧变形量的影响,而在500℃退火时的析出与冷轧变形量无关;此外,Fe/Si含量比高的3003铝合金箔可获得大量细小且均匀分布的第二相粒子。
The microstructures evolution of 3003 aluminum alloy foil during preparing process was investigated by hardness and electric resistance test ,XRD analysis ,OM ,SEM and TEM observation. The effects of Fe and Si tramp elements on the microstructures and properties of 3003 alloy were also discussed. The results show that the solid solution of Mn decreases,and the α-Al（Fe,Mn） Si phases increase with increasing the （Fe ＋ Si） content. A large amount of manganiferous particles precipitate during annealing at 300℃ and 500℃ after cold-rolled deformation. At 300℃, the precipitates are affected by the cold reduction. However,the precipitation is independent of the cold -rolled deformation at 500℃. Moreover, a large amount of fine and uniformly distributed second phase particles are observed in 3003 aluminum alloy foils with higher Fe/Si ratio.
