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.

Productivity‐Driven Optimization of Laser Powder Bed Fusion Parameters for IN718 Superalloy: Process Control, Microstructure, and Mechanical Properties

Advanced Engineering Materials, EarlyView.
This study demonstrates how optimizing laser power, scanning speed, and hatching distance in laser powder bed fusion can boost the productivity of Inconel 718 manufacturing by up to 29% while maintaining mechanical integrity. The work delivers a validated process window and cost–time analysis, offering industry‐ready guidelines for efficient additive ...

Resistance Rapid Heating of Aluminum Coatings in an Extreme High Vacuum–Adequate Atmosphere for Hot Stamping

Advanced Engineering Materials, EarlyView.
The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.

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 ...

Dielectric Barrier Discharge Plasma Deoxidation of Natively Oxide Layer of Copper Powders in a Fluidized Bed

Advanced Engineering Materials, EarlyView.
This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Nuclear Shell Structure and Nuclear Density

Nature, 1950
THE existence of the shell structure of nuclei has been derived from a considerable variety of empirical facts (stability and abundance of nuclei, spin, magnetic moment, quadrupole moment, isomerism and β-decay)1. The closed shells of neutrons as well as of protons correspond to the numbers 2, 8, 20, 28, 50, 82, 126.

Nuclear Antigenic Structures

Scandinavian Journal of Rheumatology, 1985
Nuclear envelope. Improved light and electron microscopic techniques have provided a vast amount of new information about nuclear structures in the last decade (4). It is well recognized that the nucleus is surrounded by a double membrane consisting of (a) an outer layer which is continuous with the endoplasmic reticulum and the many important ...

Nuclear envelope structure

Current Opinion in Cell Biology, 1992
The past 18 months have seen significant advances in our knowledge of the constituents of the nuclear envelope, their interactions during interphase and the mechanisms involved in their mitotic dynamics. Although most of the new data are in general agreement with, and contribute detail to, our traditional image of the nuclear envelope, a few ...

Nuclear binding and nuclear structure

International Journal of Mass Spectrometry, 2013
Abstract Binding in atomic nuclei reflects all the nucleonic interactions in the nucleus. These interactions determine the average nuclear potential and the residual interactions that give rise to correlated behavior in nuclei. Therefore the study of nuclear binding energies can shed light on those interactions and on the emergence of coherence and ...

Nuclear Shell Structure and Nuclear Density

Proceedings of the Physical Society. Section A, 1951
Correlations between the nuclear shell structure and the density distribution are analysed on the assumption that the former is associated with the successive appearance of particles of higher angular momentum. General requirements for the possible form of the nuclear density distribution are derived.
