首次提出了一次热变形工艺。采用这种新方法，从MQPA带状粉末制备了高性能各向异性NdFeB磁体。研究了温度和变形量对合金硬磁性能的影响。在最佳工艺条件下，获得了（BH）max为28 MGOe的NdFeB。
Single stroke hot deformation process was introduced for the first time in this study. A high performance anisotropic NdFeB magnet was fabricated by this new method from MQPA ribbon powder. Principal factors that influenced hard magnetic properties, temperature and deformation percentage, were investigated. Under optimum conditions, NdFeB with (BH)max of 28 MGOe was obtained.
