We applied synchrotron single-crystal X-ray diffraction in a diamond anvil cell at 48-51 GPa and first-principles theoretical calculations to study the crystal structure of solid atomic iodine at high pressure. We report the synthesis of two phases o

Microstructure and Stress Mapping in 3D at Industrially Relevant Degrees of Plastic Deformation

Autor: Henningsson, Axel, Kutsal, Mustafacan, Wright, Jonathan P., Ludwig, Wolfgang, Sørensen, Henning Osholm, Hall, Stephen A., Winther, Grethe, Poulsen, Henning F.

Strength, ductility, and failure properties of metals are tailored by plastic deformation routes. Predicting these properties requires modeling of the structural dynamics and stress evolution taking place on several length scales. Progress has been h

Grain-level effects on in-situ deformation-induced phase transformations in a complex-phase steel using 3DXRD and EBSD

Autor: Ball, James A. D., Davis, Claire, Slater, Carl, Vashishtha, Himanshu, Said, Mohammed, Hébrard, Louis, Steinhilber, Florian, Wright, Jonathan P., Connolley, Thomas, Michalik, Stefan, Collins, David M.

Publikováno v: Acta Materialia 265 (2024) 119608

A novel complex-phase steel alloy is conceived with a deliberately unstable austenite, $\gamma$, phase that enables the deformation-induced martensitic transformations (DIMT) to be explored at low levels of plastic strain. The DIMT was thus explored,

Synthesis of Ultra-Incompressible Carbon Nitrides Featuring Three-Dimensional Frameworks of CN4 Tetrahedra Recoverable at Ambient Conditions

More than thirty years ago, carbon nitrides featuring 3D frameworks of tetrahedral CN4 units were identified as one of the great aspirations of materials science, expected to have a hardness greater than or comparable to diamond. Since then, no unamb

Report

Non-destructive determination of phase, size, and strain of individual grains in polycrystalline photovoltaic materials

Autor: Lucas, Mariana Mar, Ramos, Tiago, Jørgensen, Peter S., Canulescu, Stela, Kenesei, Peter, Wright, Jonathan, Poulsen, Henning F., Andreasen, Jens W.

We demonstrate a non-destructive approach to provide structural properties on the grain level for the absorber layer of kesterite solar cells. Kesterite solar cells are notoriously difficult to characterize structurally due to the co-existence of sev
