Abstract

Several criteria are available in literature for selection of alloy compositions for metallic glasses. We have analyzed characteristics of glass-forming compositions numbering around 1000 in terms of three parameters. They refer toelectron to atom ratio (e/a), volume ratio (VR) and radius ratio (RR). Venn-Diagrams created based on these parameters for Fe-, Cu-, Zr-, Ti-, La-, Mg-, Co-, Al-, Ni- and Pd-based alloy systems will be presented. Relative importance of e/a, VR, and RR will be indicated. Having done this, we would like to understand the process of stabilization of Bulk Metallic Glasses (BMGs) in terms of Fermi surface (FS) and Pseudo Brillioun zone (PBZ) interaction.
