| Abstract Scope |
Experimental confirmation of short-range order in metallic glass primarily based on diffraction (x-ray, neutron or electron), which provides information about average coordination numbers and bond lengths within a glass structure, with little insight into the local atomic stoichiometry or the stability of these structures. In the field of metal cluster physics “Magic numbers” in abundance in the mass spectra of ablated or evaporated metallic cluster ions from a bulk material provide information on cluster stoichiometry and stability, from which aspects of short-to-medium-range structure may also be inferred. By producing cluster ions from samples of well-known binary (bulk) metallic glass-forming alloys, experimental insights into which short- and medium-range structures may exhibit intrinsically greater electronic or chemical stability have been gained. This new approach to probing the amorphous structure supplements both diffraction and simulation data, providing further understanding of amorphous structure stability in specific alloy compositions. |
