The Development of Alkoxy-Based Sol -Gel Processing for Magnetoresistive Manganite Thin Films
… for bulk, polycrystalline powders. Typical grain sizes started at 10--15 nm, increasing to 20--25 nm by 750°C. For films deposited on Si(100), magnetoresistance was observed in specimens heat treated at 700°C and 750°C, and for platinized-Si(100), 650°C, 700°C, and …

The development of alkoxy-based sol-gel processing for magnetoresistive manganite thin films
… amorphous coatings. Conversion into a fine-grain, polycrystalline microstructure occurred above 600°C on platinized-Si(100) and above 650°C on Si(100). The cubic lattice parameters of the films (i.e., a = ∼ 3.90 Å) were in excellent agreement with values published in the literature for bulk, …

High temperature fracture behaviour of laser-powder bed fusion produced nickel superalloy
… service. The process however produces a unique microstructure not present in wrought counterparts and the high temperature performance of L-PBF parts remains insufficiently documented. Understanding these characteristics is critical, given the extreme operating conditions encountered by …

Correlation between structure, doping and performance of thermoelectric materials
… precipitate system and layered-and-correlated grain microstructure—have been proposed and synthesized in ZnO. The mechanisms iii governing the nature of thermal behavior in these structures have been explored and quantified. Due to strong phonon scattering, the nano-precipitates can reduce the …

The microstructural evolution of fatigue cracks in FCC metals
… compared the measured strain to the microstructure. Overall, the strain measured via DIC and EBSD was only weakly correlated to the density of planar slip bands in the microstructure. The second set of experiments concerned the dislocation structure around crack tips. This set of …
