最近，生产了(Fe-Co)-B-Si-Nb块体金属玻璃(BMG)。这种 BMG 具有高玻璃形成能力 (GFA) 以及良好的机械和磁性性能。这些合金结合了功能材料和结构材料的优点。软磁性能可以通过纳米晶化来增强。为了强制纳米结晶，在起始组合物中添加少量的铜。在本文中，选择了 {[(Fe0.5Co0.5)0.75Si0.05B0.20]0.96Nb0.04}100–xCux 玻璃合金 (x= 1、2 和 3) 进行研究。评估了这些合金的 GFA 和热稳定性。研究了热处理过程中的结晶对这些合金的相演化和磁性能（包括Ms、Hc和Tc）的影响。相位分析是借助使用传输配置中的同步加速器辐射现场记录的 X 射线衍射图案来完成的。
Recently, (Fe-Co)-B-Si-Nb bulk metallic glasses (BMGs) were produced. Such BMGs exhibit high glass-forming ability (GFA) as well as good mechanical and magnetic properties. These alloys combine the advantages of functional and structural materials. The soft magnetic properties can be enhanced by nanocrystallization. To force the nanocrystallization, small content of Cu was added to the starting composition. In this article, {[(Fe0.5Co0.5)0.75Si0.05B0.20]0.96Nb0.04}100–xCuxglassy alloys (x= 1, 2, and 3) were chosen for investigation. The GFA and the thermal stability of these alloys were evaluated. The effects of crystallization during heat-treatment processes on the phase evolution and the magnetic properties, includingMs,Hc,andTc, in these alloys were investigated. The phase analyses were done with the help of the X-ray diffraction patterns recordedin situby using the synchrotron radiation in transmission configuration.
