Abstract : The report describes the determination of the thermodynamic properties of the bcc solid solution of titanium-copper alloys. In conjunction with this investigation, a new technique was developed for the measurement of thermodynamic activity at high temperatures by the use of a triple Knudsen effusion cell, enriched isotopes of the pure solute, and a time-of-flight mass spectrometer.
