Structure and properties of transition-metal--metalloid glasses based on refractory metals
The structure and properties of several new transition-metal--metalloid (T/sub 1-x/M/sub x/) metallic glasses based on refractory transition metals (e.g., Mo, W, Ru, etc.) have been systematically investigated as a function of composition. The structure of the alloys has been investigated by x-ray diffraction methods and measurements of superconducting properties, electrical resistivity, density, hardness, and mechanical behavior were carried out. These data are used in developing a novel description of the structure of T/sub 1-x/M/sub x/ glasses. The experimental evidence suggests that an ideal amorphous phase forms at a specific composition x/sub c/ and that this phase has a well-defined atomic short-range order. For metallic glasses having xx/sub c/. This novel picture can explain the variation of many properties of these glasses with metalloid concentration.
