Fe73.5Si13.5B9Nb3Au1 ribbons have been prepared by rapid cooling on a single copper
wheel with different speeds of wheel of 10, 20, 30, and 40 m/s. The as-spun samples are
amorphous. Upon annealing, the nanocrystalline phases are formed. Increasing the cooling rate
leads to thinner ribbons, higher crystallization activation energy and crystallization volume
fraction of the a-Fe(Si) phase, slightly increasing Curie temperature and soft magnetic properties
of annealed ribbons. The large magnetic entropy change is observed for sample with v = 30 m/s.
The mechanisms of the effects have been discussed. |
