1Development of a database for the prediction of phases in Pt-based Superalloys:Cr-Pt-Ru显示文摘Work has been ongoing in building a thermodynamic database for the prediction of phase equilibria in Pt-based superalloys. The alloys are being developed for high temperature applications in aggressive environments. The database will aid the design of alloys by enabling the calculation of the composition and proportions of phases present in alloys of differ- ent compositions. In order to extend this database, a preliminary assessment of the Cr-Pt-Ru system has been undertaken, using a combination of Pandat and MTDATA software. As a first step, it was necessary to provide thermodynamic models for the three associated binary systems. Owing to a lack of thermodynamic information for these systems, the binary as- sessments were based on phase diagrams available in the literature. Using recent experimental phase equilibria data for the ternary system, a preliminary assessment of the Cr-Pt-Ru system has been produced. In this preliminary assessment, simpli- fied models were employed for the L12 and sigma phases with a view to extending the descriptions as new experimental in- formation becomes available.A.Watson L.A.Cornish R.Süss 2006Rare Metals2006,25,5:0
