When the B content is 0.05%, the coarse dendrite is found in cast structure of alloy, When B content is up to 0.1%, dendrites grow further and secondary dendrites appear.

实验结果表明，合金的组织随着B加入量的增加变得粗大，当B加入量为0.05%时出现粗大枝晶，0.1%时枝晶进一步长大且出现二次枝晶。

An electromagnetic stirrer of the rotation type was employed under similar conditions, the as-cast structure of metals solidified with and without electromagnetic stirring were compared.

实验采用旋转型电磁搅拌器。在相似条件下，液态金属在电磁搅拌下凝固与不经电磁搅拌凝固的铸态组织进行对比。
