摘要
Recently,steady magnetic fields avail-able 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 re-viewed. These processed objects primarily include superconducting,magnetic,metallic and nanome-ter-scaled materials. It has been found that a high magnetic field can effectively align grains when fab-ricating the magnetic and non-magnetic materials and make inclusions migrate in a molten metal. The mechanism is discussed from the theoretical view-point of magnetization energy.
