Abstract

The kinetics of crystallization of amorphous melt-spun Nd13Fe79B8 alloy induced by thermal treatment was studied by differential scanning calorimetry, scanning and transmission electron microscopy and magnetic measurements. The optimization of coercivity through controlled crystallization is explained as a consequence of the crystallization kinetic behaviour. Optimal materials are obtained by annealing the amorphous alloys at temperatures in the range 950-1000 K for times of the order of 15 min. After that heat treatment a fully crystallized material is obtained with a mean grain size of about 60 nm and a coercivity of 1.4 T. © 1992.
