Castability, in a narrow sense, means the formability of a particular liquid metal into a desired shape by transformation from liquid to solid. Considering the importance of recycling, the reuse of returned scrap should be related to castability. In addition, glass forming ability should also be studied for bulk amorphous metals, as it is very closely related to crack formation during casting. This paper reports a study on the castability of Cu-base bulk amorphous alloy made by conventional vacuum induction melting. The effects of specimen thickness, number of remeltings, and mold temperature were investigated. A test mold for thin plate specimens was designed in order to evaluate the liquid formability of the alloy. Mold filling was good for 2 mm specimens; however, many cracks were observed after cooling. While the mold cavities were not fully filled for 1 mm specimens, no cracks could be found. The glass forming ability also became worse with increasing number of remeltings; this worsening is believed to be caused by the increase in oxygen content.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
