Rapid Growth and Magnetic Properties of Fe₇CO₃ Intermetallic Compound

Abstract:

By drop tube and melt spinning techniques, rapid growth of Fe₇Co₃ intermetallic compound has been realized. The microstructures and nucleation characteristics under different cooling rates are investigated. With the increase of cooling rate, Fe₇Co₃ intermetallic compound grains are refined in both rapid growth manners. Experimental observation and theoretical analysis indicate that the nucleation rate in single-roller quenching is much greater than that in free-fall method when the cooling rate is under a same level. The comparison of magnetic property between the alloy ribbons and other dimensional magnetic material were made. The superior soft magnetic properties of Fe-Co alloy ribbons changes sensitively with the cooling rate, which is mainly decided by the wheel velocity.
