概要

• 論文の詳細を見る

• Development of industrial nanocomposite permanent magnets (NCPM) is reviewed with a particular emphasis on rare-earth-iron-based materials. After a brief description of the basic concepts concerning NCPM, leading discoveries of iron-based NCPM are reviewed. The impact of recent development of high-coercivity Nd-Fe-B-Ti-C isotropic NCPM powders that are industrially produced by applying strip casting process for rapid solidification is described. Short comments on bulk NCPM and empirical efforts toward anisotropic NCPM are also included. Application aspects of the industrial NCPM are discussed.
