The improvements are due mainly to significant reduction of lattice thermal conductivity ($\\kappa_{l}$), which was in turn attributed to nanoparticle precipitates. However, a fundamental understanding of various phonon scattering mechanisms within the bulk alloy is still lacking. In this work, we apply the newly-developed density-functional-theory (DFT)-based compressive sensing lattice dynamics (CSLD) approach to model latt","authors_text":"James M. Hodges, Maria K. Y.
