description | Fe계 연자성 합금의 제조방법이 제공된다. 본 발명의 일 실시예에 따른 Fe계 연자성 합금은 실험식 FeaBbCcCud(단, a, b, c 및 d는 해당 원소의 at%(atomic percent)이며, 78.5≤a≤86, 13.5≤b+c≤21, 0.5≤d≤1.5임)로 표시되는 Fe계 초기합금을 제조하는 단계, 및 상기 Fe계 초기합금을 열처리하는 단계를 포함하고, 상기 열처리는 상기 Fe계 초기합금의 결정화 개시온도(Tx1) 보다 높은 제1열처리 온도로 수행되는 1차 열처리와, 상기 1차 열처리 후 상기 제1열처리 온도 보다 낮은 제2열처리 온도로 수행되는 2차 열처리를 포함하여 제조된다. 이에 의하면, 구현된 Fe계 연자성 합금이 높은 최대자속밀도 및 투자율을 가지면서도 낮은 보자력, 낮은 코어로스 등 자기손실이 크게 감소한 Fe계 연자성 합금을 제조하기에 용이하다. 또한, 동일한 조건으로 수십, 수백 회 Fe계 연자성 합금을 반복 생산하더라도 연자성 합금 간 자기적 물성이 균일하도록 구현 가능하여 대량생산에 매우 적합하다. 나아가 이를 통해 구현된 Fe계 연자성 합금은 높은 포화자속밀도 및 현저히 낮은 자기손실을 가짐에 따라서 각종 코일부품이나 전자파차폐재의 자성재료로서 널리 응용될 수 있다.
A method for manufacturing an Fe-based soft magnetic alloy is provided. An Fe-based soft magnetic alloy according to one embodiment of the present invention is manufactured by the method comprising the steps of: preparing an Fe-based initial alloy represented by the experimental formula FeaBbCcCud (However, a, b, c, and d are each an atomic percent (at%) of the corresponding element, 78.5≤a≤86, 13.5≤b+c≤21, 0.5≤d≤1.5); and performing heat treatment on the Fe-based initial alloy. The heat treatment includes a first heat treatment performed at a first heat treatment temperature higher than a crystallization start temperature (Tx1) of the Fe-based initial alloy, and a second heat treatment performed at a second heat treatment temperature lower than the first heat treatment temperature after the first heat treatment. Accordingly, it is easy to manufacture an Fe-based soft magnetic alloy having a significantly reduced magnetic loss such as low coercivity and low core loss and so on while the Fe-based soft magnetic alloy implemented has a high maximum magnetic flux density and permeability. In addition, even if Fe-based soft magnetic alloys are repeatedly produced tens or hundreds of times under the same conditions, it is possible to achieve uniform magnetic properties between the soft magnetic alloys, which is very suitable for mass production. Furthermore, the Fe-based soft magnetic alloy implemented through this procedure has a high saturation magnetic flux density and remarkably low magnetic loss, and thus can be widely applied as a magnetic material for various coil components or electromagnetic wave shielding materials. |
