Crystal Structure Investigation of Ferritic 73Fe24Cr2Si0.8Mn0.1Ni Steel for Multi-purpose Structural Material Applications

open access: yesInternational Journal of Technology, 2018
Microstructural identification of synthesized steel with significant local content has been carried out. Alloy ingot was prepared using a casting technique. The samples were then formed into bulk steel by a machining process.

Extended Anionic Network in Mixed‐Valent Nitridocobaltates(I/II) LnCo2N2 (Ln = La, Pr, Nd)

open access: yesAdvanced Science, EarlyView.
This study presents the high‐pressure synthesis of LnCo2N2 (Ln = La, Pr, Nd) with Co in mixed valent states of +I/+II. The compounds demonstrate the stabilization of a nitridocobaltate with extended anionic Co–N layers where Co is threefold coordinated.

Diffraction Plane Dependence of Micro Residual Stresses in Uniaxially Extended Carbon Steels

open access: yesAtom Indonesia, 2010
In the stress measurement using X-ray or neutron diffraction, an elastic anisotropy as well as a plastic anisotropy of crystal must be carefully considered.

Magnetism in crystalline rare-earth compounds [PDF]

open access: yes, 2011
In this thesis we investigate the magnetism of a selection of crystalline mate- rials that display fascinating macroscopic properties, largely due to the complex behaviour of rare-earth ions. The technique of choice is diffraction; shown to pro- vide the

Charge‐Transfer‐Mediated Boron Magneto‐Ionics: Towards Voltage‐Driven Multi‐Ion Transport

open access: yesAdvanced Science, EarlyView.
This study demonstrates voltage‐driven multi‐ion transport in FeBO systems, revealing simultaneous motion of B, Fe, and O ions enabled by charge‐transfer effects. By tuning oxidation states through oxygen incorporation, we achieve a transition from electrostatic‐like to electrochemical magneto‐ionic behavior. The findings establish boron magneto‐ionics,

New single-toroidal sintered diamond anvil and assembly for high pressure neutron diffraction

open access: yesNuclear Analysis
In-situ high pressure neutron diffraction experiments, which require a large volume samples, remain challenging, particularly when generating simultaneous high pressure-temperature (P-T) conditions.

Phonon‐Driven Tetrahedral Tilts Enable Ultralow Bulk Thermal Expansion and Interstitial Oxide‐Ion Migration in Phenacite Solid Electrolytes

open access: yesAdvanced Science, EarlyView.
This work demonstrates a design paradigm of phonon‐driven negative‐thermal‐expansion (NTE) flexible framework that exploits the intrinsic lattice flexibility of NTE frameworks to simultaneously suppress thermal expansion and activate oxide‐ion conduction, offering a promising strategy to mitigate TEC mismatch in solid‐state ionic devices.

A Compact Cryogenic Environment for In Situ Neutron Diffraction Under Mechanical Loading

open access: yesQuantum Beam Science
Understanding the deformation mechanisms of materials at cryogenic temperatures is crucial for cryogenic engineering applications. In situ neutron diffraction is a powerful technique for probing such mechanisms under cryogenic conditions.

Neutron reflectivity and grazing angle diffraction

open access: yesJournal of Research of the National Institute of Standards and Technology, 1993
Over the last 10 years, neutron reflectivity has emerged as a powerful technique for the investigation of surface and interfacial phenomena in many different fields. In this paper, a short review of some of the work on neutron reflectivity and grazing-angle diffraction as well as a description of the current and planned neutron rcflectometers at NIST ...

An integrated approach to the determination and consequences of residual stress on the fatigue performance of welded aircraft structures [PDF]

open access: yes, 2005
Although residual stress in welded structures and components has long been known to have an effect on their fatigue performance, access to reliable, spatially accurate residual stress field data has been limited.
