Ingot solidification is in the mold under high temperature inside, and difficult to direct observation and control.
钢锭凝固是在铸型内的高温状态下进行的，难以直接观察和控制。

As-cast microstructure of Mg alloy AZ31 ingot and its annealing technology have been researched hence certain reference for direct plastic deformation from as-cast microstructure of Mg alloy AZ31.
The surface and inner qualities of aluminum alloy ingot by electromagnetic casting (EMC) have been investigated and compared with those of the direct casting (DC) one.
