In this paper, it introduces the principle of hydrogen decrepitation reaction, the production process, the advantages over traditional process for NdFeB alloy strip, and the factors that can influence it. The effects of hydrogen decrepitation process and traditional process on the properties and structure of the magnets are compared. It expounds and analyzes the importance of the technology of hydrogen decrepitation and jet milling in the current production process of NdFeB magnets.
