Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, EarlyView.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Effect of Postweld Heat Treatment on Laser‐Welded Duplex Stainless Steel: Crystallographic Patterns and Fatigue Behavior

steel research international, EarlyView.
Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

Modelling Approaches for an Asymmetrical Six-Phase Machine [PDF]

With currently available power electronic devices, the power range of a single three-phase power converter is limited well below the power ratings foreseen for remote offshore wind turbines. A solution is to use multiphase systems.

Time‐resolved 3D imaging opportunities with XMPI at ForMAX

Journal of Synchrotron Radiation, EarlyView.
The first implementation of X‐ray multi‐projection imaging (XMPI) at the ForMAX beamline (MAX IV) enables the acquisition of multiple projections simultaneously without requiring sample rotation. This approach facilitates volumetric studies of fast dynamics at frame rates of 12.5 kHz with micrometre resolution, with the potential of even higher speeds,

Endometrial microbiota‐targeted therapies for chronic endometritis‐associated recurrent implantation failure and their impact on IVF outcomes: A systematic review and methodological quality assessment

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Microbiota‐targeted interventions may improve implantation and pregnancy outcomes in women with chronic endometritis‐associated recurrent implantation failure. However, current evidence is constrained by heterogeneous study designs, nonstandardized diagnostic criteria, small cohort sizes, and limited adjustment for confounding factors.
