摘　　要：从多个角度,将Al-Fe合金中金属间化合物形成过程的研究成果进行分类.二元Al-Fe合金相组成的影响因素包含以成分为主的热力学因素及以冷却速度为主的动力学因素.而目前的研究中,对于热力学因素影响的研究大都没有考虑动力学因素的影响,因而往往与实际结果有所偏差;对于动力学的研究中由于加工方法本身的局限性,因而在平衡近似下的动力学与热力学模型都无法适用.未来在该领域内的研究,既要满足理论模型中的平衡假设条件,也要考虑热力学与动力学因素的综合作用,且应加强对于相变机理方面的研究.Al-Fe alloy is a novel aluminum alloy of prospective application whose optimized processing requires a comprehensive research upon the phase transition involved in depth. In this work,previous results on factors affecting the formation of intermetallic phases in the alloys are reviewed from multiple perspectives. The formation of intermetallics depends on both thermodynamic factors and kinetic factors. So far the theoretical models on these aspects are based on assumption of equilibrium transition, whereas the interaction between thermodynamic and kinetic factorsis largely ignored. Based on these comments, brief proposals are made for further research in this field in the future.
