The Relation Between Bulk Modulus and Relative Enthalpy: a Broad-Based Thermodynamic Analysis and a Case Study on Aluminum

Abstract

By postulating a linear relationship between logarithmic bulk modulus and relative enthalpy, we have developed in this paper a thermodynamic framework that provides a link between thermal properties and bulk modulus under constant pressure. The proposed model could be used in analyzing the consistency of various bulk modulus estimates of aluminum through an integrated treatment of its thermal and elastic properties.
