A theoretical study of compound formation in liquid Cu-Hf alloys at high temperatures

The possible compounds existing in the liquid Cu-Hf alloy at 1650 and 1873 K have been verified using a statistical mechanical model based on complex formation in compound forming liquid alloys. CuHf2 is the more stable compound at high temperatures though its existence appear more predominant at lower concentrations of Hf. Other compounds, Cu4Hf and Cu5Hf also exist throughout the concentration range but its influence on the thermodynamic properties of the liquid Cu-Hf alloy is low.
