ABSTRACTFor the Ni-base TaC eutectics, it has been shown previously that carbide volume fraction is a strong function of Ta/C ratio. Now in a number of Ni,Cr-TaC and Ni,Cr,Al-TaC alloys, Cr has been observed to have only a small influence on volume fraction of carbide, while Al has a major influence acting to decrease the volume fraction. The Al present in the matrix causes the phase equilibrium to approach that of a much greater Ta/C ratio. This analysis has been extended to more complex NiTaC alloys as well. For the simple Ni-Cr-Ta-C alloys, creep behavior has been studied as a function of volume fraction of carbide.Other carbide systems have been evaluated as well, including TiC and NbC. A general understanding of volume fraction differences between these systems and TaC can be reached by consideration of ideal solution behavior and the appropriate phase diagrams.

Mobile Order

Experimental solubilities are reported at 25.0°C for phenanthrene dissolved in 41 different organic nonelectrolyte solvents containing ether, carbonyl, hydroxy, chloro, amino, ester, methyl and tert-butyl functional groups. Results of these measurements are used to test the applications and limitations of expressions derived from Mobile Order theory. For the 31 solvents for which predictions could be made, computations show that Mobile Order theory does provide fairly reasonable estimates of the saturation mole fraction solubilities. Average absolute deviation between predicted and observed values is 41.3% (excluding acetonitrile). In comparison, the average absolute deviation is 1610% when ideal solution behavior is assumed. Also reported are experimental solubilities at 26°C for pyrene dissolved in 1-hexanol, 1-heptanol, ethylbenzene, aniline, and 2-butanone.Key words: phenanthrene solubilities, organic nonelectrolyte solvents, solubility predictions.

Experimental solubilities are reported at 25.0°C for fluoranthene dissolved in 36 different organic nonelectrolyte solvents containing ester, ether, hydroxy, chloro, methyl, and tert-butyl functional groups. Results of these measurements are used to test the applications and limitations of expressions derived from Mobile Order theory. For the 28 solvents for which predictions could be made, computations show that Mobile Order theory does provide fairly reasonable estimates of the saturation mole fraction solubilities. Average absolute deviation between predicted and observed values is 53%. In comparison, the average absolute deviation is 1574% when ideal solution behavior is assumed.Key words: fluoranthene solubilities, organic nonelectrolyte solvents, solubility predictions.

Experimental solubilities are reported at 25.0°C for hexachlorobenzene dissolved in 42 different organic nonelectrolyte solvents containing ether-, chloro-, hydroxy-, ester, methyl-, and tert-butyl-functional groups. Results of these measurements are used to test the applications and limitations of expressions derived from Mobile Order model. For the 33 solvents for which predictions could be made computations show that Mobile Order model does provide fairly reasonable estimates of the saturation mole fraction solubilities. Average absolute deviation between predicted and observed values is 210%. In comparison, the average absolute deviation is 2 060% when ideal solution behavior is assumed.Key words: hexachlorobenzene solubilities, organic nonelectrolyte solvents, solubility predictions.
