| 摘 要： | Different Mo contents have been added into traditional Finemet alloy to form Fe73.5Cu1Nb3-x MoxSil3B9.5( x = 0 - 3) alloys. The change in DC and AC magnetic properties with Mo for Nb substimtlon was investigated. The results show that, with adding Mo, although the DC relative permeability decreases and the coercive force increases slightly,the saturation flux density Bs can be increased, and the core loss of the alloy can be decreased. The AC permeability of samples contained Mo is higher than that of alloy without Mo content. Fe73.sCu1Nb1Mo2Si13B9.5 alloy has the highest saturation flux density Bs. Fe73.sCu1Nb2Mo1Si13B9.5 alloy has the best frequency dependence on the AC permeability and core loss.

| Abstract: | Different Mo contents have been added into traditional Finemet alloy to form Fe73.5Cu1Nb3- x Mo x Si13B9.5 ( x =0～3) alloys. The change in DC and AC magnetic properties with Mo for Nb substitution was investigated. The results show that, with adding Mo, although the DC relative permeability decreases and the coercive force increases slightly, the saturation flux density B S can be increased, and the core loss of the alloy can be decreased. The AC permeability of samples contained Mo is higher than that of alloy without Mo content. Fe73.5Cu1Nb1Mo2Si13B9.5 alloy has the highest saturation flux density B S. Fe73.5Cu1Nb2Mo1Si13B9.5 alloy has the best frequency dependence on the AC permeability and core loss. |
