چکیده انگلیسی
The flow behaviour in the supercooled liquid region of a low-pressure die-cast Mg65Cu25Y10 (at.%) bulk metallic glass over a range of temperatures (150-170 °C) and strain rates (10â3 to 10â1 sâ1) was investigated by tensile testing. In most cases, the maximum elongation obtained was 1300% without failure due to the limitations of the maximum traveling distance of the tensile testing machine. The flow behaviour was analysed in terms of the free volume model with the results used in conjunction with experimental data to construct deformation maps in terms of peak stress, strain rate and temperature for identifying the homogeneous and inhomogeneous deformation zones under various testing conditions.
