摘要：
New bulk metallic glasses (BMG) have been synthesized in the Mg-Cu-RE systems (RE = Y, Gd) with high critical diameter. In order to determine the glass forming range of these ternary systems, the calculation of the onset of driving forces (ODF) has been performed and has shown a large composition range for BMG formation. The synthesis of particular compositions in this domain has shown that all the produced alloys present a high glass forming ability (GFA) measured by DSC experiments. The ODF model, synthesized alloys by mould casting, characterization by X-ray diffraction and DSC techniques are presented.
