英文摘要	MM14Fe79.9B6.1 magnets were prepared by conventional sintering method. The Curie temperature of the sintered MM2Fe14B magnet was about 210 degrees C. When the sintering temperature increased from 1010 degrees C to 1030 degrees C, the density of the magnet increased from 6.85 g/cm(3) to 7.52 g/cm(3). After the first stage tempering at 900 degrees C, the (BH) max and H-cj had a slight increase. The maximum value of (BH)(max) = 7.6 MGOe and H-cj = 1080 Oe was obtained when sintered at 1010 degrees C and tempering at 900 degrees C, respectively. The grain size grew very large when the sintering temperature increased to 1050 degrees C, and the magnetic properties deteriorated rapidly. La reduced by similar to 7.5 at. % in grains, which is almost equal to the increased percentage of Nd. That is mainly because La-Fe-B is very difficult to form the 2: 14: 1 phase. (C) 2017 Author(s).
