Abstract

The linear chemical‐physical theory (LCPT) model for liquid metal solution thermodynamics has been extended to the determination of the liquidus curves for binary intermetallic compound‐forming systems. The equations developed include corrections to the observed melting point temperature and heat of fusion for compounds that dissociate partially on melting. The primary advantages of the LCPT model for solid‐liquid equilibria are the small number of physically realistic parameters required, ease of implementation, and wide applicability. In addition, the model also permits the incorporation of compounds in modeling the liquidus curves that are not necessary for representing the liquid‐phase thermodynamic properties. For the seven systems studied, the agreement between calculated and experimentally measured liquidus curves is quite good.
