MICROSTRUCTURE AND MAGNETIC PROPERTIES OF SINTERED ND-FE-B MAGNETS

Popis výsledku v původním jazyce

Sintered Nd-Fe-B permanent magnets with a medium coercive force were fabricated using a strip-casting alloy prepared at the VŠB-TU Ostrava. Powders prepared by hydrogen decrepitation and subsequent milling were compacted in a magnetic field and sinteredat ? = 1340 ? (for 2 h). The sintered blanks were subjected to optimum heat treatment at 500?? for 2 h followed by quenching in gaseous nitrogen. Detailed studies of the microstructure, phase composition and magnetic properties of the heat treated samples were performed. The composition and structure of the samples were examined using X-ray diffraction (XRD) and scanning electron microscopy JEOL JSM-6610LV. Magnetic properties were measured using vibrating-sample magnetometer and hysteresisgraph AMT-4.The higher coercive force was reached after aging at 500oC, which was performed after cooling from sintering temperature to room temperature.
