Production of Mg-Based Bulk Metallic Glass Composites with High Magnesium Content

Abstract:

In this work, in-situ BMG composites based on the Mg-Ni-Gd system with high Mg content (>80 at. %) were produced by copper mould gravity and injection casting methods. The morphology, distribution and volume fraction of the crystalline phases that form in the amorphous matrix was shown to be influenced by cooling rate, composition and casting parameters. Hence, the mechanical properties and deformation behaviour of Mg-Ni-RE BMG composites can be tailored by controlling the microstructure generated during casting.
