随着电力和电子技术的飞速发展，相应的元器件向高频化、小型化、高效率和节能的方向发展，从而对元器件用材料也提出了更高要求。为此，本文概述了冶金部钢铁研究总院近年来所研究的用于开关电源、脉冲变压器、传感器、电流互感器和电感器等方面的非晶软磁合金的性能及其应用概况。 With the rapid development of electric power and electronic technology, the corresponding components have been developed in the direction of high frequency, miniaturization, high efficiency and energy saving, thereby putting higher demands on the materials for components. For this reason, this article summarizes the properties and applications of amorphous soft magnetic alloys used in the fields of switching power supply, pulse transformers, sensors, current transformers and inductors studied by the Research Institute of Iron and Steel of Ministry of Metallurgy in recent years.
