Abstract：
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.
