Microstrucural characterization of gas atomized Fe73.5Si13.5B9Nb3Cu1 and Fe97Si3 alloys

▶ Two FeSi-base alloys as precursors for small dimension soft magnets. ▶ Small particles rapidly solidified by gas atomisation. ▶ Increase effective magnetic anisotropy constant by alloying segregation. ▶ Magnetic hardenning due to volume decrease.
