Phonon transport and thermodynamic properties of nanostructured materials have been investigated and utilized to improve thermoelectric performance for various materials. In nanostructures, phonon transport is completely different from that in bulk materials and results in dramatic enhancement in the thermoelectric performance. This article reviews the impact of nanostructuring on the phonon transport and mainly focuses on phononic crystal nanostructures, in which the wave nature of phonons also plays an important role. We demonstrate that it is important to efficiently scatter thermal phonons, which distribute to wide range of frequencies, with different phonon scattering mechanisms in the spatial domain. We also demonstrate an enhancement of thermoelectric property of polycrystalline thin films by phononic crystal patterning. [doi:10.2320/jinstmet.JA201504]

Mo-Si-B-TiC alloys are expected to be a candidate for an ultrahigh-temperature material beyond Ni-base superalloys. This work quanti- tatively investigated the microstructure of a Mo-Si-B-TiC alloy with the composition of Mo-5Si-10B-10TiC (65Mo alloy) (at%) produced via arc-melting and tilt-casting techniques. The alloy was composed of four constituent phases: Mo solid solution (Mo ss ), Mo 5 SiB 2 (T 2 ), (Ti, Mo)C x , (Mo, Ti) 2 C, and their eutectic (or peritecteutectic) phases. The compositions of the constituent phases were determined by elec- tron beam micro analyzer (EPMA). Scanning electron microscopy – backscattered electron diffraction (SEM-EBSD) measurements revealed that T 2 and (Ti, Mo)C x phases have orientation relationships with Mo phase: { 1¯10 } Mo // (001) T2 , < 111 > Mo //< 001 > T2 and { 1¯10 } Mo // { 1¯11 } (Ti , Mo)Cx , < 111 > Mo //< 001 > (Ti,Mo)Cx . Furthermore, the three-dimensional SEM observation with the combination of the focused ion beam (FIB) serial sectioning technique demonstrated that the T 2 phase had a thin plate shape with the orientation of (001) as plate surfaces and of { 100 } as side ones.
