4.1. Synthesis and physical characterization
With Ca as the major alloying component in the BMG used in
this study, it was strategically decided to develop compositions
that maintain a high GFA, while maximizing the Zn content—the
least corrosion-prone species present in the alloys. Ca contents as
low as 50 at.% and Zn contents as high as 30 at.% were successfully
alloyed and cast to produce BMG samples.
Shifting from Ca-rich compositions, moving further from the
deep ternary eutectic reaction (according to Ref. [43]), the liquidus
temperatures and the intervals between the melting and liquidus
temperatures increased (Fig. 3 and Table 1).
The GFA of the alloys studied herein tended to be inversely related
to the liquidus temperature and the relative volume fraction
of the higher melting point constituents, as indicated by the area
