A study of Pr-Fe-B magnets produced by a low-cost powder method and the hydrogen decrepitation process
Sintered Pr-based magnets were produced using a new laboratory technique for powder handling. Unlike the conventional procedure for preparing sintered permanent magnets in the laboratory, the powder technique used in this investigation does not require a glove box.

| description | Sintered Pr-based magnets were produced using a new laboratory technique for powder handling. Unlike the conventional procedure for preparing sintered permanent magnets in the laboratory, the powder technique used in this investigation does not require a glove box. The effects of processing parameters on the magnetic properties of Pr-based sintered magnets prepared using the hydrogen decrepitation process have been studied. Specifically, the effects of sintering temperature and milling time for processing Pr16Fe76B8 magnets have been investigated. Pr16Fe76B8 magnets with the best magnetic properties were sintered between 1015 °C to 1075 °C. |
