【Abstract】

<正> Hydrogen decrepitation (HD)) has been used as an efficient and economical method in producing coarse powder of NdFeB alloys. Combining of hydrogen decrepitation (HD) and jet milling (JM), High performance NdFeB magnets can be produced. Hydrogen is a useful assistant in NdFeB industry. This article studied hydrogen's effects on the Nd-Dy-Fe-B magnets, with the Nd-rich composition. It showed that hydrogen accelerated the oxidation rate of the coarse Nd-Dy-Fe-B powder after HD process and dropped the sinter
