Computer Based Methods for Thermodynamic Analysis of Materials Processing
Abstract
The data base previously developed for multicomponent SIALON Ceramic phase diagrams has been expanded to cover Ce2O3 additions. The Ce2O3-SiO2 and Ce2O3-Si3N4 systems have been computed. Isothermal sections in the MgO-Si3N4- SiO2, Y2O3-SiO2-Si3N4 and Ce2O3-SiO2-Si3N4 systems near 2000 K have been computed and compared with limited experimental data. A data base has also been developed for calculating binary, ternary and multi-component phases diagrams for III-V and II-VI compound systems. The trajectory of ordering temperatures for A2/B2 and B2/DO3 reactions has been computed along the Fe3Si-Fe3Al composition path in the BCC of the Fe-Al-Si system and compared with experiment. The two phase (fcc + bcc) fields for disordered phases in the iron-aluminum- nickel, iron-aluminum-manganese, and the iron-nickel-manganese system between 900 and 1200 C. Construction of a data base covering fluoride systems consisting of systems containing ZrF4 which are employed to synthesize fluoride glasses has been initiated.
