A Powerful Optimization Technique for the Calculation of Binary Phase Diagrams Using Partial Phase Diagram Data

The interaction parameters for variousphases in the Ti-W and Pd-W systems were calcula-ted using phase diagram information by meansof a numerical procedure.The approach differssignificantly from the trial and error methodand has the advantage of being very robust inthe sense that one can make full use of theaccurate experimental phase diagram data anddeal with situations which are difficult oreven impossible for the trial and error method.Using calculated parameters and lattice stabilityvalues for Ti,W and Pd given in literature,the diagrams of the above systems were recalcula-ted.The results are in good agreement withexperimental information.
