The developed automatic fabrication system comprised three component functions: weighing, alloying, and casting. The measurement error of automatic weighing specimen was about less 1 pct for Zr-based master alloys (approximately 30 g). Especially, sufficient stirrer effect of arc-melting ingot for homogeneity can be achieved by the development of sinusoidal arcing and applying magnetic field. In order to achieve superior homogeneity of the glass structure with no secondary phase (i.e., an intermetallic compound with a high melting temperature), a prealloying process should be advisable. In this study, high reliability of the density and mechanical properties of automatic processed cast glassy alloys (CGAs) was successfully obtained. The developed automatic fabrication process has a potential to accelerate the industrial application of CGAs in the near future.
