Recent advances in mechanical properties of sintered NdFeB magnets

In recent years, with the development of sintered NdFeB magnets, NdFeB has been widely used in many high-tech fields. The mechanical properties of sintered NdFeB magnets are an important index to evaluate their overall performances, and the study on the mechanical properties of sintered NdFeB magnets has been paid more and more attention. In this review article, the research progress on mechanical properties of sintered NdFeB magnets in recent years is reviewed. Firstly, the effects of structural characteristics, fracture behavior and addition of alloyed elements on mechanical properties of sintered NdFeB magnets are discussed. The methods to improve the mechanical properties of sintered NdFeB magnets are then summarized. Finally, some views on the challenges and future development of NdFeB permanent magnet materials are also presented. [Display omitted]
