New processing possibilities for highly toughened metallic glass matrix composites with tensile ductility

New processing possibilities are explored for a semi-solidly-processed bulk metallic glass matrix composite based on the ZrTiNbCuBe system. Thermoplastic processing in the supercooled liquid region, extensive room temperature cold-rolling, and tensile ductility with work-hardening are all achieved. This research demonstrates that bulk metallic glass matrix composites have potential that far exceeds high tensile ductility and ultra-high toughness.
