[ 1 ] - آثار مغناطوالاستیکی در آهنرباهای نانوکامپوزیتNd4Fe77.5B18.5

  In this research, magnetostriction and thermal expansion of polymer-bonded Nd4Fe77.5B18.5 nano-composites are studied using strain gage method. The effect of sintering on samples is also studied. X-ray diffraction patterns and SEM pictures of the original and annealed samples show that the grain size of a -Fe and Fe3B soft magnetic phases in amorphous matrix increases and mechanical hardness ...
