| Abstract: | The effect of crystallization annealing process on magnetic properties and property consistency of Fe73.5Cu1Nb3Si13.5B9 nanocrystalline soft magnetic materials was researched.It shows that good magnetic properties and high property consistency are obtained through grade crystallization annealing,due to that crystallization annealing temperature is effectively controlled for the crystallization precipitation of α-Fe(Si) nanocrystalline phase crystallization.To prevent sample oxidation,H2 was chosen to fill the furnace.It also helps to improve magnetic properties and consistency of the trial batch due to its high thermal conductivity and reduction characteristics. |
