| Abstract Scope |
The availability/reproducibility of our own developed metallic glassy microparts fabrication process were investigated. We proposed the process where a single spherical particle is used as a raw material for fabricating microparts. Mono-dispersed [(Fe0.5Co0.5)0.75Si0.05B0.2]96Nb4 metallic glassy particles with diameters of several hundred micro meter scales were successfully prepared by a container-less quenching technique called the pulsated orifice ejection method (POEM). The glassy states of the particles prepared at the same batch were confirmed to be almost identical and it was clarified that the particles had technological advantages as raw materials for microparts. In addition, several kinds of microparts were successfully fabricated through the micro viscous flow processing, in which a single POEM particle is directly shaped into the final product. It was revealed that metallic glassy microparts with nearly the same geometric shape with almost the identical thermal/processing histories can be fabricated, verifying the availability of our proposed sequential processes. |
