中文摘要:

最近,从没有致冷剂的超导的磁铁可得到的稳定的磁场开创新方法处理材料。在这篇论文,主要结果由使用一个高磁场处理几先进材料获得了被考察。这些处理目标首先包括超导、磁性、金属性、可伸缩纳米的材料。当制作磁性的 andnon 磁性的材料时,一个高磁场罐头有效地排列谷物,这被发现了并且让包括在熔融的金属移居。机制从磁化精力的理论观点被讨论。

英文摘要:

Recently, steady magnetic fields available from cryogen-free superconducting magnets open up new ways to process materials. In this paper, the main results obtained by using a high magnetic field to process several advanced materials are reviewed. These processed objects primarily include superconducting, magnetic, metallic and nanometer-scaled materials. It has been found that a high magnetic field can effectively align grains when fabricating the magnetic and non-magnetic materials and make inclusions migrate in a molten metal. The mechanism is discussed from the theoretical viewpoint of magnetization energy.
