The thermodynamics of solid-solid interfaces in systems of fixed mass
The textbook approach to interfacial excess quantities, due to Gibbs, is valid only at
fixed volume. In the present work we develop an alternative approach to interfacial
excess quantities, valid at fixed mass. For solid-solid interfaces this has several
advantages over the Gibbs treatment such as (a) non-zero interfacial excess volumes
appear naturally in the treatment, (b) analogues of the bulk phase Maxwell relations
are readily obtained, and (c) formulae for the pressure dependence and temperature
dependence of the interfacial tension are derived in a transparent way.
