摘要 The 3003/4045 aluminum alloys cladding hollow billets with the diameter of 60 mm and external thickness of 3 mm are fabricated by horizontal electromagnetic continuous casting.The surface features of ingots and microstructures of the bonding interface are observed.The results show that cladding hollow billets combine the external and internal layers by metallurgical bonding without mixing when the pouring temperature of the external liquid metal is 903 K.The diffusion region with the thickness of 25 μm can be seen clearly,where mutual diffusion of Si and Mn atoms takes place. In addition,the intermetallic compound Al_(12)(FeMn)_3Si_2 is formed in the interface.
