Metallic Glass Components Produced by Rapid-Rotation Centrifugal Casting

摘要

"Rapid-Rotation Centrifugal Casting Process" was applied to manufacturing the amorphous bulk metallic glassy alloys (BMGs) components. The molten alloys were poured into copper mold with rotation speed over 3000rpm which can cause 100 times as much centrifugalpressurization force as gravity. The samples such as small gear, screw, biomedical artificial tooth-root model and gripper of endoscope of Zr or Fe alloy systems were successfully fabricated within only a few seconds at one process with more cheap cost.
