金属玻璃具有良好的可成形性和可转移性，以及较高的机械性能和优异的磁性能，有可能应用于精密微零件。因此，需要对体积进行精确控制的原材料进行高精度加工。本文采用脉冲孔喷射法（POEM）制备了fe - co基金属玻璃的单尺寸球形颗粒，并研究了其在玻璃化转变温度下的微成形性能。采用脉冲孔喷射法（POEM）获得了直径为200 ~ 500 μm的铁钴基金属玻璃单粒径球形颗粒。颗粒的XRD谱图显示只有宽峰，没有结晶峰。粒子的亮场透射电镜图像和选定区域的衍射模式显示只有晕状模式表明完全非晶相。DSC曲线显示过冷液区为ΔT=48 K，通过等温DSC可以构造TTT曲线。
Metallic glasses are potentially applied for accurate micro parts because of their good formability and transferability as well as high mechanical properties and excellent magnetic properties. So the raw materials that the volume is precisely controlled are needed for a highly accurate processing. In this study, mono-sized spherical particles of Fe-Co-based metallic glass were prepared by Pulsated Orifice Ejection Method (POEM) and the capabilities of their micro-forming process in the glass transition temperature were investigated. Mono-sized spherical particles of Fe-Co-based metallic glass particles with 200-500 μm of diameter have been obtained by Pulsated Orifice Ejection Method (POEM). The XRD pattern of the particles shows only broad peaks without any crystalline peak. A bright field TEM image of the particles and the selected area diffraction patterns shows only halo patterns that indicate fully amorphous phase. DSC curve shows that supercooled liquid region was ΔT=48 K and a TTT curve can be constructed by isothermal DSC.
