磁性金属玻璃研究进展

磁性金属玻璃是一种新型的磁性材料,它具有大的玻璃形成能力和良好的热稳定性,只需很低的临界冷却速率即可获得很大尺寸的金属玻璃。与传统的磁性材料相比,磁性金属玻璃的有关性能更加优异,它具有高的饱和磁化强度,低的矫顽力,高的磁导率以及大的磁致伸缩系数,而且,在其液态过冷区内具有超塑性,利用这一特点,可以将其加工成为各种高精密度形状复杂的磁性器件。

Progress in Research of Magnetic Glassy Alloys

Magnetic glassy alloy is a new kind of magnetic material which has large glassy forming ability and good thermal stability.And glassy alloy with large thickness has been made with rather low critical cooling rate.Compared with traditional magnetic materials,magnetic glassy alloys have high saturation magnetization,low coercivity,extremely high permeability and large magnetostriction,as well as superplasticity in the supercooled liquid region which is of great significance to make different kind of complicated and high precise magnetic devices.
