In situ X-ray diffraction during loading and unloading is used to investigate the effects of
grain size (GS) on the stress-induced nanoscale phase transition (PT) mechanism in …

Microstructure control in functional materials draws from a historical reserve rich in
established theory and experimental observation of metallurgy. Methods such as rapid …

Local crystal structure, crystal orientation, and crystal deformation can all be probed by Laue
diffraction using a submicron x-ray beam. This technique, employed at a synchrotron facility …

Structural transformations in crystalline solids are increasingly the basis of the functional
behavior of materials. Recently, in diverse alloy systems, both low hysteresis and …

Phase decomposition is a well-known process leading to the formation of two-phase
mixtures. Here we show that a strain imposed on a ferroelastic crystal promotes the …

Interfaces play important roles in the performance of nanostructured thermoelectric
materials. However, our understanding of the atomic-scale structure of these interfaces is …

Nanostructured thermoelectric materials offer promising levels of conversion efficiency due
to enhanced phonon scattering at interfaces, and a good understanding of the formation and …

Nucleation and growth precipitation experiments were conducted on samples of In-alloyed
Bi2Te3 with a starting composition of Bi1. 65In0. 35Te3 (7at.% In) to investigate the phase …

A mathematical description of crystal structure is proposed consisting of two parts: the
underlying translational periodicity and the distinct atomic positions up to the symmetry …

On the materials scale, thermoelectric efficiency is defined by the dimensionless figure of
merit zT. This value is made up of three material components in the form zT= Tα 2/ρκ, where …
