ENTHALPIES OF FORMATION OF LIQUID AND SOLID BINARY ALLOYS BASED ON 3d METALS - 1. ALLOYS OF SCANDIUM, TITANIUM AND VANADIUM.

Model predictions are presented for heats of formation of binary intermetallic compounds of Sc, Ti or V with arbitrary metal partners, and for heats of mixing and solution of the corresponding liquid alloy systems. Predicted values are compared with the existing experimental data as well as with qualitative information derived from phase diagram information. A complete set of binary phase diagrams based on Sc, Ti or V is presented in schematic form. Differences between experimental and calculated enthalpy values are discussed.
