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.

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Sieve algorithms for the shortest vector problem are practical

Journal of Mathematical Cryptology, 2008
The most famous lattice problem is the Shortest Vector Problem (SVP), which has many applications in cryptology. The best approximation algorithms known for SVP in high dimension rely on a subroutine for exact SVP in low dimension.

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Coherent Networks of Si Nanocrystals: Tunable Collective Resonances with Narrow Spectral Widths

Advanced Photonics Research, 2021
The ultralong coherent networks of Si nanocrystals (NCs) via lattice‐enhanced dipole–dipole coupling and the formation of disordered arrays of phase‐correlated field hotspots are studied.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

On Alexandrov lattices

International Journal of Mathematics and Mathematical Sciences, 1993
By an Alexandrov lattice we mean a δ normal lattice of subsets of an abstract set X, such that the set of ℒ-regular countably additive bounded measures is sequentially closed in the set of ℒ-regular finitely additive bounded measures on the algebra ...

An Attack Bound for Small Multiplicative Inverse of φ(N) mod e with a Composed Prime Sum p + q Using Sublattice Based Techniques

Cryptography, 2018
In this paper, we gave an attack on RSA (Rivest⁻Shamir⁻Adleman) Cryptosystem when φ ( N ) has small multiplicative inverse modulo e and the prime sum p + q is of the form p + q = 2 n k 0 + k 1 , where n is a ...

On congruence lattices of lattices [PDF]

Acta Mathematica Academiae Scientiarum Hungaricae, 1962
If K is a lattice, then let | denote the lattice of all congruence relations of K. It is known (see [1]) that O(K) is a distributive lattice satisfying some continuity properties (see below). It is natural to ask about the lattice-theoretical characterization of O(K).
