一、引言 铁基非晶材料是一种性能良好的软磁材料,它具有高的磁饱和B_s,低的损耗,且原料来源广,价格便宜。几年来发展很快。目前铁基非晶合金的损耗约为晶态3％硅钢的1/10,作为潜在的节能材料是十分诱人的,但这个数值距理论值还相差很远(理论上应低100倍左右),为了进一步提高铁基非晶材料的性能、降低损耗,控制好晶化转变过程的工艺是很重要的。结晶度就是控制这一工艺的一个重要参数,它对材料的性能影响很大。
I. INTRODUCTION Iron-based amorphous material is a kind of soft magnetic material with good performance. It has high magnetic saturation B_s, low loss, wide source of raw materials and low price. In recent years the rapid development. At present, the loss of iron-based amorphous alloy is about 1/10 of the crystalline 3% silicon steel, which is very attractive as a potential energy-saving material. However, this value is far from the theoretical value (in theory, it should be about 100 times lower) , In order to further improve the performance of iron-based amorphous materials, reduce the loss, the process of controlling the crystallization transition is very important. Crystallinity is an important parameter in controlling this process, which has a great effect on the material properties.
