Abstract:Bulk metallic glasses (BMGs) have been found in many Zr-based multi-component alloys. After discussions on the diffraction characteristics corresponding to the Fermi surfaces-Brillouin zone interaction effect in the Zr-based BMG-related phases, we point out that the 2k(f)approximate tok(p) rule is satisfied when the conduction electron concentration of Zr is 1.5. These BMG- and quasicrystal-related phases, sharing nearly the same conduction electron concentrations per atom (e/a), are e/a-constant phases in a given alloy system. Such an e/a-based criterion is then applied to the Zr-Al-Ni system and a series of BMGs with constant e/a ratio, equal to 1.5, are obtained by suction casting. (C) 2003 Elsevier B.V.
