Particle analysis and properties of mechanically alloyed Nd16Fe76−xTixB8

Nanocrystalline Nd₁₆Fe_76−xTi_xB₈ hard magnetic powders were prepared by mechanical alloying and respective heat treatment at 973–1073 K /30–60 min. The nanocrystalline hard magnetic powders were investigated by the NanoSight Halo LM10^TM Nanoparticle Analysis System, AFM, SEM and Mössbauer spectrometry. The nanocrystals have average size of 40 nm and the crystals form agglomerates with an average size of about 180 nm. Halo^TM, AFM and SEM techniques are the complementary methods, which give comparable results.
