Abstract
Using ball milling and single direction pressing, we can produce high perfo rmance NdFeB sintered' magnets. The oxygen content of sintered magnets can be controlled under 1500x10(-6) and the magnetic performance can be improve d by using low oxygen processing. The high performance NdFeB sintered magne ts with B-r=(1.4+/-0.2)T, (j)H(c)greater than or equal to 796kA/m and (BH)( max)=(390+/-16) kJ/m(3), have been batch produced.
