Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Advanced Engineering Materials, EarlyView.New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data
Advanced Engineering Materials, EarlyView.Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

Physical Review Letters, 1989
As with amorphous solids, the absence of periodic order makes it difficult to calculate the electronic structure of liquids. However, unlike the solid case, techniques for handling correlated topological disorder are standard in liquid theory. We show how recasting tight-binding models into random-matrix problems makes the band-structure-in-a-liquid ...

Proceedings of the Physical Society, 1963
A calculation of the valence and conduction bands of diamond has been carried out, using a set of eight localized bond orbitals, four bonding and four antibonding, made up from simple tetrahedral orbitals. Bloch functions have been set up in the usual way and overlap among them neglected.

By analogy to electron waves in a crystal, electromagnetic waves in a 3-D periodic dielectric structure should be described by band theory. The idea of photonic band structure1 is rapidly2–5 gaining acceptance. The concepts of reciprocal space, Brillouin zones, dispersion relations, Bloch wave functions, Van Hove singularities, etc., are now being ...

We have investigated the structure of the collective bands in within our deformed configuration mixing (DCM) shell model based on Hartree - Fock states. In our model, the single particle orbits , , and are taken as the configuration space with as the core. A modified Kuo interaction for this basis space is used in our calculation.
