obviously changes. For 3003/4004 clad ingot, without electromagnetic stirring, the solidification structure of 4004 aluminum alloy near the interface is coarse dendrite, when electromagnetic stirring is used, the solidification structure of 4004 aluminum alloy changes into non-dendrite crystal. For 5056/AZ91 clad ingot, without electromagnetic stirring, the of intermetallic compounds congregate......
