Notes:
The heat of fusion and the specific heats of the solid and liquid have been experimentally determined for a Ti60Cr40 alloy. The data is used to evaluate the Gibbs free energy difference, ΔG, between the liquid and the β phase as a function of temperature to verify a reported spontaneous vitrification (SV) of the β phase in Ti-Cr alloys. The results show that SV of an undistorted β phase in the Ti60Cr40 alloy at 873 K is not feasible because ΔG is positive at the temperature. However, ΔG may become negative with additional excess free energy to the β phase in the form of defects.
