Abstract : The purpose of the study is the thermodynamic investigation of titanium, Ti, over a range of temperatures up to 6000K and pressures up to 1000 atmospheres. Two sets of equilibrium composition equations are used--one representing a pure gas phase, the other a heteorogeneous system of gas and condensed (i.e., solid or liquid) titanium. The gas phase of the heterogeneous Chemical system, like the homogeneous gas phase, comprises 3 gaseous species. The results of the computational program are presented in both tabular and graphic form. The latter comprises (a) a conventional Mollier diagram in which specific enthalpy is plotted against specific entropy, with cross plots of temperature, pressure, and molecular weight or moles of condensed titanium, (b) a plot of volume versus temperature for titanium, and (c) a plot of vaporization temperature for titanium, aluminum, and graphite at various pressures.
