THERMODYNAMICS OF ALLOYS VAPOUR PRESSURE STUDIES
Abstract
As part of a program of studies of the thermodynamic properties of alloy systems, measurements have been made of the vapor pressures of a number of pure metals and their alloys. The torsion-effusion technique has been employed and its applicability to alloy studies has been demonstrated. New vapor pressure measurements have been made on solid Cd (480 - 570 K), liquid Bi (820 - 1010 K) and liquid Th (780 - 920 K) and the results are assessed and compared with those of other workers. Bismuth vapor pressures have been measured over a wide range of liquid Ag-Bi alloys and the results used to compute the thermodynamic properties of the system at 1000 K. The rather unusual characteristics of these are discussed and it is suggested that they are attributable to the change of bonding and coordination of Bi on alloying. A similar evaluation of the thermodynamic properties of liquid Ag-Pb alloys is also presented and discussed. Preliminary measurements on solid and liquid Ag-Th alloys are described.
