摘要：
The effect of neodymium and boron content was studied for the Nd7+xFe79-x+y-zB14-yTiz (x = 0, 1, 2; y = 0, 1, 2; z = 0, 4)system. The alloys were prepared by melt-spinning and suction casting. The highest magnetic properties (H-J(c) = 648 kA/m, J(r) = 972 mT, (BH)(max) = 143 kJ/m(3)) were achieved for the melt-spun Nd8Fe74B14Ti4 alloy. This was caused by Ti addition and was related to the convenient combination of the phase constitution and fine crystallite size in the range of 15-30 nm.
