摘要：
Ca65Mg15Zn20 bulk metallic glass samples of dimensions 3.15 min x 7 mm x 125 min were prepared using a repetitive low-pressure die-casting technique. It was found that charge temperature, injection pressure and fluid velocity at the mould gate were important parameters for controlling the length, porosity and the presence of crystalline phases in the as-cast samples. A processing map was generated which shows the optimum region of melt temperature and casting pressure for generating the highest quality castings of these dimensions. (c) 2007 Elsevier B.V.
