Abstract： Explosive welding technology was used to prepare a composite plate consisting ofa 5 083 aluminum alloy cover plate，B steel substrate， and a 1 0 6 0 pure aluminum intermediate layer. The microscopic structure and composition of the composite plate interface were studied through instrumental analysis.The experimental results indicatethatintheexplosive weld jointregion，intermetaliccompoundssignificantly increasedtheoverallhardness of the interface， with the maximum hardness observed at the metal compound at the aluminum-steel bonding interface.This aluminum-steel composite plate successfully combines the corrosion resistance and lightweight advantages of aluminum alloy with the high hardness and wear resistance benefits of steel.
Key words： explosive welding; aluminum-aluminum-steel composite plate； microscopic observation; EDS; hardness

在經(jīng)濟飛速發(fā)展的今天，傳統(tǒng)單一材料已難滿足現(xiàn)代工業(yè)對材料性能的多元化需求，因此，為滿足單一材料同時擁有多種性能，研究出一種通過焊接的方式使兩種或者多種金屬結(jié)合，即爆炸焊。（剩余5296字）
