Enthalpy and Curie temperature relaxation effects in FeSiB-CuNb alloys prepared at different quenching rates

摘要

Structural relaxation in FeSiB-CuNb alloys is studied from enthalpic and Curie temperature effects. Enthalpy release and Curie temperature changes can be fitted to an exponential behaviour as a function of the annealing time by using two Different relaxation times. For ribbons melt-spun at different wheel speed, no significant differences in structural relaxation Behaviour are found.
