TL;DR: In this paper, the authors demonstrate phonon properties with fundamental equations and show examples how the phonon calculations are applied in materials science, and demonstrate the importance of first principles phonon calculation in dynamical behaviors and thermal properties.

TL;DR: In this article, the Hall-Petch relation is discussed separately for the yield stress of polycrystalline metals and for the flow stress of deformed metals for a grain size range from about 20 nm to hundreds of micrometers.

TL;DR: In this paper, it has been shown that submicrometer-grained structures may be produced in a wide range of materials (e.g. pure metals, metallic alloys including superalloys, intermetallics, semiconductors) by subjecting these materials to a very high plastic strain using either equal-channel angular (ECA) pressing or torsion straining under high pressure.

TL;DR: In this article, the potential of metallic glasses as structural materials is assessed and a wide-ranging comparison with conventional engineering materials shows metallic glasses to be restricted to niche applications, but with outstanding properties awaiting wider application, for example in micro electro-mechanical systems devices.
