On the effect of Ti on Oxidation Behaviour of a Polycrystalline Nickel-based Superalloy [PDF]
, 2018 Titanium is commonly added to nickel superalloys but has a well-documented detrimental effect on oxidation resistance. The present work constitutes the first atomistic-scale quantitative measurements of grain boundary and bulk compositions in the oxide ...

GRAIN BOUNDARIES AND ANTIPHASE BOUNDARIES IN GaAs
Le Journal de Physique Colloques, 1988 Bicrystals of GaAs with a predetermined orientation relationships between the grains have been produced by growing GaAs epilayers on substrates cut from Czochralski-grown germanium bicrystals. Grain boundaries have also been generated in GaAs epilayers grown on (110) Ge substrate.

Advanced Engineering Materials, EarlyView.Experiments for reinforcing the diffusion bonding plane by the oxide dispersion strengthening effect are presented. Small ceramic particles (0.5 and 50 μm, respectively) are incorporated. Furthermore, ceramic particles help to penetrate stable passivation layers, enabling atomic diffusion across bonding planes. Since a ceramic–metallic interface cannot

Advanced Engineering Materials, EarlyView.In the present study, metastable CrMnNi steels with varying chemical compositions and a concomitantly altered stacking fault energy are processed via directed energy deposition and afterwards tested via tensile tests at different temperatures. The present study shows the influence of the manufacturing process on the elemental deformation mechanisms for

Grain boundary oxidation and fatigue crack growth at elevated temperatures [PDF]
Fatigue crack growth rate at elevated temperatures can be accelerated by grain boundary oxidation. Grain boundary oxidation kinetics and the statistical distribution of grain boundary oxide penetration depth were studied.

A study on grain boundary barrier layer solid aluminum capacitors
Open CeramicsThis study employs solid-state and chemical plating methods to fabricate aluminum grain boundary capacitors using Al@CuO composite materials. The materials were prepared under varying compaction pressures (200 psi, 500 psi, and 700 psi) and thermal ...
