Notes:
Ca65Mg15Zn20 bulk metallic glass samples of dimensions 3.15 × 7 × 125 mm were preparedusing an inverted low-pressure die-casting technique. It was found that charge temperature, andinjection pressure were important parameters for controlling the length, porosity and degree ofcrystallinity in the as-cast samples. A processing map was generated illustrating the optimum castingtemperature and pressure range for generating the highest quality castings. These samples wereground into tensile samples in compliance with ASTM E8-04 and deformed in the supercooled liquid(SCL) region (105 to 135 °C) at constant strain rates from 10-3 to 10-4 s-1. Reported are the effects ofthese parameters on the deformation behaviour of the Ca65Mg15Zn20 BMG
