Effects of Ingot Cooling Ways on the Microstructure and Magnetic Property of NdFeB Magnet AITranslate
Abstract AITranslate
The two ingots were prepared by sheet double-sided cooling and plate single-sided cooling,respectively in the process of preparing Nd14.9Fe77.8Al0.3Cu0.2B6.8 magnetic material.Their microstructures and phase characteristics were analyzed,and their corresponding magnet samples were investigated on microstructure and magnetic property.The results show that the ingot prepared by sheet double-sided cooling is of more uniform grain size and less α-Fe phase than the ingot prepared by plate single-sided cooling.The magnet sample from the former ingot is of more homogeneous structure with 0.02 T higher residual magnetic flux density（Br）,2.5 kA/m higher intrinsic coercivity（Hcj）,and 2.8 kJ/m3 higher maximum energy product than the magnet sample from the latter ingot.
