摘要

利用扫描电子显微镜、能谱分析以及3D有限元模拟等手段研究族聚第二相与表面亮条形成之间的关系。研究表明：铸轧铝箔毛料中的AlFeSi粒子呈族状分布在毛料表面或近表面。硬质团族粒子与冷轧时的纳米油膜相互作用，会使粒子附近的润滑油膜破裂，导致粒子与破裂区域的铝膜基体发生严重变形，与周边产生色差，形成表面亮条。%Scanning electron microscopy and X-ray energy dispersive spectrum analysis show that the clusters of intermetallic AlFeSi particle are distributed on or near the aluminum foil stock surfaces heterogeneously. 3D finite element modeling shows that these clusters of hard particles induce the fracture of the nano-scale lubricant oil film at first and further lead to severe deformation in the nearby aluminum foil substrate along the rolling direction. Consequently, the optical property in this region differs from that in the surroundings, resulting in surface defects.
