Description
The crystallisation kinetics of MM2.5Fe79B18.5 (MM=Mischmetal), was followed by means of Moessabuer effect experiments at constant acceleration, Moessbauer thermal scan, thermomagnetic and calorimetric measurements. It was determined that the as-quenched ribbons are amorphous with a Tc of 668 K and the crystallisation, at low heating rates, occurs in two steps: in the first step, it precipitates a dilute α-(Fe, RE) solid solution, while in the second Fe2B and more α-(Fe, RE) are crystallised from the remnant Fe-impoverished amorphous matrix
