摘　　要：再生铝中的富铁相显著降低了其性能,限制了其在生产生活中的应用。本文综述了再生铝中杂质元素的来源、存在形式以及富铁相带来的影响,并分析了富铁相的去除方法,以及无法去除的铁元素所形成富铁相的形貌调控办法。添加稀土元素、锰和硅,可以改变富铁相的形貌,并抑制针状铁相的生成。此外,添加元素与硼的协同作用可使富铁相的长径比减少90%,结合热力学和动力学,从原子半径角度分析了不同元素的除铁机制。同时,本文分析了数值模型、计算机辅助CALPHAD模拟和人工智能等新兴技术的应用,提出利用人工智能技术与实验和模拟数据相结合的双向循环优化模式,提升再生铝合金性能,促进其实现更广泛的工业应用。The presence of Fe-rich phases in recycled aluminum significantly degrades its performance,limiting its application in production and daily life.This paper reviewed the sources and forms of impurity elements in recycled aluminum,as well as the detrimental effects of Fe-rich phases.It also analyzed the morphological control of the iron-rich phase formed by the iron element that cannot be removed.The addition of rare earth elements,manganese,and silicon can modify the morphology of Fe-rich phases and suppress the formation of needle-like iron phases.Furthermore,the synergistic effect of additive elements and boron can reduce the aspect ratio of Fe-rich phases by 90%.The mechanisms of iron removal by different elements were discussed based on thermodynamics,kinetics,and atomic radius considerations.Additionally,the applications of emerging technologies,such as numerical modeling,CALPHAD-based computer simulations,and artificial intelligence,were examined.A dual-cycle optimization model that integrates AI techniques with experimental and simulation data was proposed to enhance the performance of recycled aluminum alloys,enabling their broader industrial application.
