摘要
Different Mo contents have been added into traditional Finemet alloy to form Fe 73.5 Cu 1Nb 3- x Mo x Si 13 B 9.5 ( 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. Fe 73.5 Cu 1Nb 1Mo 2Si 13 B 9.5 alloy has the highest saturation flux density B S. Fe 73.5 Cu 1Nb 2Mo 1Si 13 B 9.5 alloy has the best frequency dependence on the AC permeability and core loss.
