Evidence of a local BCC‐type coordination of cobalt in FCC taenite of iron meteorites

Meteoritics &Planetary Science, EarlyView.
Abstract Ni, Co, and Fe K‐edge X‐ray absorption fine structure (XAFS) measurements were performed, revealing an unexpected local structure around Co in well‐known iron and stony‐iron meteorites. Cobalt is enriched in kamacite but remains in taenite at concentrations of at least 0.3 atom%.

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

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
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.

Determination of Stress Profiles in Expanded Austenite by Combining Successive Layer Removal and GI-XRD

, 2014
The present work deals with the evaluation of the residual-stress profile in expanded-austenite by successive removal steps using GI-XRD. Preliminary results indicate stresses of several GPa's from 111 and 200 diffraction lines.

Characterization of Macro/Microstructure and Corrosion Resistance of Austenitic Gas Tungsten Arc Welding Cladding

Advanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.
Cladding is a proven method that boosts the surface qualities of mechanical parts by applying a layer of more durable material over a base substrate. This work responds to the needs of offshore and pressure vessels sectors by focusing on cladding a super austenitic steel onto low‐carbon steel through gas tungsten arc welding.

Modelling the X-ray powder diffraction of nitrogen-expanded austenite using the Debye formula

, 2008
Stress-free and homogeneous samples of nitrogen-expanded austenite, a defect-rich f.c.c. structure with a high interstitial nitrogen occupancy (between 0.36 and 0.61), have been studied using X-ray powder diffraction and Debye simulations.

Self‐Expanding Cardiovascular Stents: Potentials and Challenges of Shape Memory Biomaterials

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 6, June 2026.
ABSTRACT Cardiovascular diseases affect a large portion of the global population and remain leading causes of morbidity and mortality. Endovascular stenting, a minimally invasive procedure, enables the insertion and deployment of stents to restore arterial patency without open surgery.
