Ultrafine-grained and heterostructured materials are currently of high interest due to their
superior mechanical and functional properties. Severe plastic deformation (SPD) is one of …

Atom probe tomography (APT) provides three-dimensional compositional map** with sub-
nanometre resolution. The sensitivity of APT is in the range of parts per million for all …

Grain boundaries (GBs), with their diversity in both structure and structural transitions, play
an essential role in tailoring the properties of polycrystalline materials,,,–. As a unique GB …

Many thermoelectric materials benefit from complex microstructures. Grain boundaries (GBs)
in nanocrystalline thermoelectrics cause desirable reduction in the thermal conductivity by …

Nanoprecipitation is a routine method to decrease the thermal conductivity for advancing
thermoelectric performance. However, the coarsening/Ostwald ripening of precipitates under …

Nearly all metals, alloys, ceramics, and their associated composites are polycrystalline in
nature, with grain boundaries that separate well-defined crystalline regions that influence …

The poor carrier mobility of polycrystalline Mg3Sb2 at low temperatures strongly degrades
the thermoelectric performance. Ionized impurities are initially thought to dominate charge …

Cold sintering densification and coarsening mechanisms are considered from the
perspective of the non-equilibrium chemo-mechanical process known in Earth Sciences as …

Grain boundaries (GBs) profoundly influence the properties and performance of materials,
emphasizing the importance of understanding the GB structure and phase behavior. As …

Grain boundary complexions in the Hastelloy C-22 are modified to unravel the structure–
