Abstract:
Centrifugal atomization is a rapid solidification process for producing metal powders traditionally limited to common metals and their alloys. This paper aims to introduce notable modifications in the development of centrifugal atomization as the research shift its focus to the production of novel materials such as metallic glasses. Emphasizing on the process parameters of atomization, mathematical calculations, and powder characterization, this research details the advancements in centrifugal atomization for Al-based amorphous powder production. The suitability of the centrifugal atomization cooling rate values for the production of Al-based metallic glasses was assessed using both theoretical and experimental approaches. This study has been accompanied by a comprehensive SEM, XRD, and DSC characterization analysis of the Al-based metallic glasses powders produced via centrifugal atomization. Overall, this paper summarizes the technical difficulty and application prospects of metallic glasses by centrifugal atomization and discusses the challenges and unresolved problems.
