Research Progress in Liquid-solid Compound Technology of Al/Steel Bimetal
Al/steel bimetallic composites exhibit broad application prospect in the fields of aerospace and automobile manufacturing,and strengthening of composites is the research focus and difficulty.The research status of interface strengthening of aluminum/steel bimetallic composites at home and abroad was summarized,including hot dip plating with different elements,applying magnetic field and applying ultrasonic vibration.The composite mechanism was reviewed,including the formation and growth of mesophase as well as influencing factors,and effects of type and distri-bution of mesophase on the properties.Finally,the future research direction of aluminum/steel bimetallic composites was prospected.
