In the past decade, a series of new bulk metallic glasses (MGs) with a multi component chemistry and high glass-forming ability (GFA) have been developed, including Zr-, Mg-, La-, Pd-, Ti-, and Fe-based alloy systems, using various solidification techniques; this has engendered interest in the synthesis and application of bulk MGs. In turn, the properties of these bulk MGs, the strength and anticorrosion properties of which are typically superior to those of their crystalline counterparts, have stimulated researchers to explore techniques to fabricate net-shaped bulk MG components. While some progress has been documented,(5-8) significant breakthroughs have been hindered by the less-than-optimum GFA and high viscosity that are typically associated with MGs.
