摘要
Multiphase structure including the metallic glass matrix and the primary crystalline phase(s) was found in the Gd55Co15Al30-xGex (0 <= x <= 10) alloys. It was confirmed by x-ray diffraction and energy dispersive spectroscopy that the primary crystalline phase was Gd5Ge3 when x >= 5. Based on these results, ternary bulk metallic glasses with composition of Gd52.5-53.8Co16.5-20.5Al25.7-31.0, which exhibit good glass forming ability and high thermal stability, were discovered.
