The Thermodynamics of the Titanium

One of a series of mathematical investigations of the thermodynamics of ablative materials, this study considers titanium over a range of temperatures up to 6000 deg K and pressures up to 1000 atmospheres. Two sets of equilibrium equations are used--one representing a pure gas phase, the other a heterogeneous system of gas and condensed solid or liquid titanium. The gas phase of the heterogeneous chemical system, like the homogeneous gas phase, comprises three gaseous species. Computational results 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 titantium; (b) a plot of volume versus temperature for titanium; and (c) a plot of vaporization temperature for titanium, aluminum, and graphite at various pressures. 44 pp. Ref.
