| Description | Journal: Iop Conference Series: Materials Science and Engineering $Nd_{2}Fe_{14}$B magnet powder has been fabricated by mixing Fe, B, and Nd powder based on their stoichiometric proportion at 650°C for 2 hours. Heat treatment series were applied at 720°C for one hour and continued with annealing at 100°C for 4 hours on different Nd stoichiometric variations; 26.6 %wt, 32.6 %wt, and 40.6 %wt. The results obtained from the X-ray Diffraction (XRD) phase analysis of Nd-rich Nd-Fe-B alloy suggested that the alloy has monophasic composition with hard magnetic $Nd_{2}Fe_{14}$B phase as a composition. The mean of the crystal grain size was determined using XRD analysis, while the microstructure and composition of the alloys were analyzed using the Scanning Electron Microscope – Energy Dispersive X-ray (SEM-EDX). The magnetic properties characterization were determined using the Vibrating Sample Magnetometer (VSM), which indicates that the sample with 40.6 %wt Nd was able to achieve the highest remanence of 446.50 G and BHmax of 17.83 kGOe. Despite the high remanence result, the coercivity and BHmax value of the third sample was still lower than the commercial's but has adequate potential value. |
