Synthesis of Zr-based bulk metallic glass-crystalline aluminum alloy composite by co-extrusion

The effects of co-extrusion conditions like extrusion temperature and deformation rate on the fabrication of a Zr-based bulk metallic glass-Al clad material were investigated under the extrusion ratio of 5.06. The ranges of extrusion temperature and deformation rate were varied from 658 to 703 K and from 10− 3 to 10− 1 mm/s, respectively. Both macroscopic and microstructural characterizations reveal that sound materials compatibility could be obtained under the low deformation rate-low temperature within supercooled liquid region combination, showing homogeneous distribution of the rate of cross-sectional area between core and sleeve without crack or intermetallic compound in the vicinity of the interface.
