چکیده انگلیسی
The tensile flow behavior of Mg65Cu25Y10 bulk metallic glass was investigated over a range of strain rates (10−3–10−1/s) and deformation temperatures (150–170 °C) in the supercooled liquid region. In this region, the relationship between peak flow stress, strain rate and absolute deformation temperature was described adequately by the classic Sellars–Tegart constitutive relationship. There was also a good correlation between the Zener–Hollomon parameter, Z, and the flow characteristics of the material such as the transition from Newtonian to non-Newtonian flow and maximum achievable tensile elongation; the latter was used for determining the optimum conditions for superplastic flow in the material.
