Abstract:The results of database based on the efficiency packed model for metallic glasses. The database contains the atomic radii information as well as elastic properties of the most commonly used alloying elements, permitting composition, packing efficiency and elastic property predictions to be made for binary, ternary and quaternary bulk metallic glasses. Twenty different alloys per system (binary, ternary and quaternary) experimentally reported in the literature were compared with those estimated by the database.… Show more
“…The topological model of densely packed clusters and the kinetic fragility index, m, have been used in the design of BMG in quaternary alloys systems 13 . Based on these models, several Zr-Co-Al-Ag alloys were calculated, and the effect of the partial substitution of Al for Ag in the glass forming ability was experimentally investigated.…”
The effect of the partial substitution of Al for Ag in the glass forming ability (GFA) of the Zr 57.52 Co 21.24 Al 21.24-x Ag x (x = 8, 10, 12, and 14 at. %) family alloy are reported and discussed. Cylindrical and conical ingots were obtained using the suction casting technique. It was found that the Zr 57.52 Co 21.24 Al 9.24 Ag 12 alloy showed a glassy structure, with a critical glassy diameter, D c , of 2 mm and ∆T x = 41 K. The bulk metallic glass Zr 57.52 Co 21.24 Al 9.24 Ag 12 alloy was examined using scanning electron microscopy, differential thermal analysis and mechanical compression test. This alloy showed a Young´s modulus (E) of 76.4 GPa and yield strength (σ y ) of 1.58 GPa. The Glass Forming Ability of the Zr 57.52 Co 21.24 Al 9.24 Ag 12 was explained in terms of the topological model of dense packed clusters and kinetic fragility index of the alloy.
