Abstract Scope |
This contribution reports a study of the ternary Co-Ta-B bulk metallic glasses with a constant boron content of 33 at.% and a variable Co-Ta ratio. Glassy rods with a diameter up to 2.5 mm exhibit ultimate compressive strength between 5.4 and 6.2 GPa and plastic strain between 0.5 and 3.2%, making them very attractive for some applications. The glass-forming ability and mechanical properties of the studied glasses are discussed in relationship to the alloy composition, atomic structure and interatomic bonding. The structural studies of Co-Ta-B glass have been carried out using different diffraction techniques and X-ray absorption spectroscopy as well as reverse Monte-Carlo simulation. |
