Thermodynamic calculation and experimental validation of Hf-rich glass forming compositions in Hf-Cu-Ni system

摘要: Abstract In the present work, Hafnium (Hf) based metallic glasses (MGs) have been developed with copper (Cu) and nickel (Ni) as constituent elements. Glass forming compositions in Hf-Cu-Ni ternary system predicted using widely accepted thermodynamic parameters. The resulting were subsequently validated by synthesizing ribbons melt-spun technique. Structural transformations of these studied X-ray diffraction (XRD) differential scanning calorimeter (DSC). Existence amorphous phase as-cast validates applicability approach. Further, it was observed that width supercooled liquid region (ΔTx) for varies from 28 K to 69 K. view glass ability, γ∗ parameter is discussed system.
