It is well known that interfaces in nanomaterials can act as ultra-fast short-circuit diffusion paths, as originating from local structural, chemical and/or electronic modifications at the interface. For example, the interface diffusivity of Cu in Cu/AlN nanomultilayers can be up to two orders of magnitude higher as compared to the bulk, which may promote interfacial premelting of Cu. Extensive ab

Despite decades of research, there is no agreement on the mechanisms contributing to the abnormal growth of {110}〈001〉 oriented Goss grains in Fe-Si electrical steels. Recently, it was shown that preferential dissolution of second-phase particles on the grain boundaries (GBs) near Goss grains leads to depinning and consequent abnormal growth.

The temperature dependence of elastocaloric cooling properties of a NiTi alloy with a grain size gradient, which was obtained by cold rolling and subsequent laser surface annealing, was evaluated and compared with those of coarse-grained and as-rolled NiTi. Results show that the adiabatic temperature change () and cooling efficiency of the gradient-structured NiTi are significantly enhanced over a
