摘　　要：Al/Mg双金属兼具铝和镁的性能特点,具有广阔的应用前景。然而,界面强度低是阻碍其发展与推广的主要因素,因此,如何调控界面组织从而提高其性能是本领域的研究热点。施加外场是一种工艺简单、成本低廉、影响效果显著,且能够同时改善基体和界面调控的复合铸造Al/Mg双金属组织和性能的方法,在强化双金属方面具有较大潜力。本文综述了机械振动场、超声场和电磁场3种主要外场对双金属组织和性能的影响,并展望了外场辅助下双金属界面调控的未来发展方向,为Al/Mg双金属的强化提供借鉴与思考。Al/Mg bimetals combine the advantageous properties of both aluminium and magnesium,offering broad application prospects.However,low interfacial strength remains a major obstacle to the development and widespread adoption of Al/Mg bimetals.Consequently,regulating the interfacial microstructure to enhance performance has become a key research focus in this field.The application of external fields is a method to improve the microstructure and properties of Al/Mg bimetallic composites through compound casting.This approach features simple processing,low cost,and significant effects that can simultaneously enhance both the matrix and the interface.This material shows great potential in strengthening bimetallic materials.This paper reviews the effects of three major external fields,namely,mechanical vibration fields,ultrasonic fields,and electromagnetic fields,on the microstructure and properties of bimetals.Additionally,future directions for the interfacial regulation of bimetals under external field assistance are discussed,providing insights and references for the strengthening of Al/Mg bimetals.
