Thermophysical Properties and Phase Equilibria of Materials Systems
Abstract
The objective is to improve thermal expansion, specific heat, molar volume, and bulk moduli predictions at the highest temperatures and pressures. In those regions experiments are difficult and data is often marginally reliable. In a series of papers, we have developed models for predicting these properties for a wide range of metals, ceramics and semiconductors. By considering the influence of thermal defects on thermal expansion it has been possible to provide a quantitative relationship for thermal expansion and molar volume from near absolute zero to the melting point for refractory metals aluminum and copper. Over the course of the project we have combined our improved properties with finite element methods to calculate residual stresses important for the fabrication and reliability of group Ill-V Nitride devices and tungsten carbide.
