Abstract:Mg55Y15Cu30 metallic glass powders were prepared by the mechanical alloying of
pure Mg, Y, and Cu after 10 h of milling. The thermal stability of these Mg55Y15Cu30
amorphous powders was investigated using the differential scanning calorimeter (DSC).
Tg ,Tx , and Δ Tx are 442 K, 478 K, and 36 K, respectively. The as-milled Mg55Y15Cu30
powders were then consolidated by vacuum hot pressing into disk compacts with a diameter
and thickness of 10 mm and 1 mm, respectively. This yielded bulk Mg55Y15Cu30 metallic
glas… Show more
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.
