Enhanced tensile strength and ductility of bulk metallic glasses Zr52.5Cu17.9Al10Ni14.6Ti5 via high-pressure torsion

Abstract
Zr 52.5 Cu 17.9 Al 10 Ni 14.6 Ti 5 (Vit105) Bulk metallic glass is processed by High-Pressure Torsion up to 30 rotations at room temperature, showing simultaneous enhancement of both strength (2023 MPa) and ductility (0.45%). Nano-crystal precipitates with an average size of 45 nm inside the amorphous matrix are observed after 30 turns HPT. Free volume increases from ~0.9030 Å 3 (as cast) to ~0.9275Å 3 after 30 turn HPT alloy with 2.83% (by...
