采用水冷铜模吸铸法制备了一系列直径为2mm的(Fe72Dy6B22)1-xNbx(x=0.02,0.03,0.04,0.05)和(Fe72Dy6B22)1-xTix(x=0.01,0.02,0.03,0.04)非晶合金棒,并测试了块体非晶合金的结构、热稳定性和软磁性能。结果表明:一定量的Nb、Ti的添加有助于改善合金的热稳定性和非晶形成能力。其中(Fe72Dy6B22)0.96Nb0.04的过冷液相区宽度ΔTx高达58℃,饱和磁感应强度为75.2 emu/g,该合金同时具有较大的热稳定性、较强的玻璃形成能力和较好的软磁性能。
A series of (Fe72Dy6B22) 1-xNbx (x = 0.02,0.03,0.04,0.05) and (Fe72Dy6B22) 1-xTix (x = 0.01,0.02,0.03,0.04) were prepared by water- Amorphous alloy rod, and tested the structure of bulk amorphous alloy, thermal stability and soft magnetic properties. The results show that adding a certain amount of Nb and Ti helps to improve the thermal stability and amorphous formation ability of the alloy. (Fe72Dy6B22) 0.96Nb0.04 supercooled liquid region width ΔTx as high as 58 ℃, saturation magnetic induction of 75.2 emu / g, the alloy also has greater thermal stability, strong glass forming ability and better Soft magnetic properties.
