Mechanical Properties of Zr-Al-Cu-Ni Alloy Glass at Different Quenching Condition
Published online by Cambridge University Press: 10 February 2011
Abstract
The samples of Zr56Al9Cu5Ni30 alloy were prepared by liquid-quenching. The mechanical properties depend on the cooling condition. The Hv value (25g load) is 580 for slow cooled rate sample, whereas the Hv value is over 800 for fast cooled sample. Since the fast cooling enhances the sample hardness, these samples become brittle. The brittleness is evaluated by the critical deformation energy (Ec) of collapse.
