Abstract

Stepped-diameter rods of 3- and 4mm diameter were cast to explore the effects of changing the niobium content of a previously studied Bulk Metallic Glass Composite (BMGC) alloy. 4mm specimens were found to be fully crystalline containing a B2 CuZr phase as well as a Cu10Zr7 intermetallic phase identified in XRD. 3mm specimens were found to have more varied microstructures, including one composition that produced possible core-shell structured precipitates. No amorphous material was confirmed, however DSC data suggests a phase transformation took place in the 3mm specimens that did not occur in the 4mm specimens.
