Alloy composition, fe-based nano-crystalline alloy and manufacturing method thereof, and magnetic component

Abstract

An alloy composition, a Fe-based nano-crystalline alloy and a manufacturing method thereof, and a magnetic component are disclosed. The expression of the alloy composition is FeaVαBbSicPxCyCuz and 79≤a≤91 at %, 5≤b≤13 at %, 0≤c≤8 at %, 1≤x≤8 at %, 0≤y≤5 at %, 0.4≤z≤1.4 at %, 0<α<5 at % and 0.08≤z/x≤0.8(at % is atomic percent). The Fe-based nano-crystalline alloy is manufactured by subjecting the alloy composition to crystallization heat treatment. Even if the heating speed upon crystallization heat treatment is slow, or there is a deviation in the temperature reached, a Fe-based nano-crystalline alloy with high saturation magnetic induction intensity and excellent soft magnetic property can still be easily obtained from the alloy ingredients of the present invention. Moreover, the present invention provides a magnetic component manufactured using the Fe-based nano-crystalline alloy.
