NdFeB系磁石材料の通電粉末圧延法によるバルク化

抄録

NdFeB magnet powder rapidly quenched (MQ powder) and Fe₃B/NdFeB spring magnet powder were densified by using the electrically heated powder rolling method (EPR). Although MQ powder was uniaxially pressed under high temperature by EPR, magnetization recordering did not occur. Fe₃B/NdFeB spring magnet powder was also consolidated by EPR. The resultant spring magnet retained the amorphous state.
