摘　　要：金属在熔化后,内部原子处于活跃状态。一旦金属开始冷却,原子就会随着温度的下降,而慢慢地按照一定的晶态规律有序地排列起来,形成晶体。但如果冷却过程很快,原子还来不及重新排列就被凝固住了,就会产生非晶态合金。非晶态合金与晶态合金相比,在物理性能、化学性能和机械性能方面都发生了显著变化。以Fe基合金制备的非晶态合金为例,其具有高饱和磁感应强度和低损耗的特点。采用熔融拉丝法制备的玻璃包覆非晶合金微丝,由于其具有微小的尺寸,可控的一维形状以及各向异性的电磁性能,近年来已经成为国外研究和应用的热点。文章对玻璃包覆非晶合金微丝制备技术进行了深入研究。When the metal is molten, the internal atoms are in active state. Once the metal begins to cool, the atoms are arranged in an orderly fashion and formed crystals according to certain crystalline states as the temperature drops. However, it the coohng process is very fast, the atoms can not be rearranged before they are solidified, thus producing amorphous alloy. Compared with crystalline alloys, amorphous alloys show remarkable changes in physical, chemical and mechanical properties. Taking amorphous alloy prepared by Fe based alloy as an example, it has the characteristics of high saturation magnetic flux density and low loss. The amorphous alloy micro- wires by glass coated that was made by melt drawing, because of its small size, controllable shape and one-dimensional anisotropic electromagnetic properties, in recent years it has become a hotspot of research and application in foreign countries. In this paper, the preparation technology of glass coated amorphous alloy microfilament is studied.
