Creep Deformation Estimation of Single Crystal Ni-Based Superalloy by Optimized Geometrically Necessary Dislocation Density Evaluation

Metals
In the framework of high temperature components, the need to evaluate the accumulated creep damage during service life is fundamental to extend the life of components which are currently deemed as scrap as per design intent.

Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

Limnology and Oceanography: Methods, EarlyView.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

Microstructure Characterization of Bending Effects in 304L Stainless Steel Cladded with Low‐Alloy Steel Weld

steel research international, EarlyView.
Prebending of 304L/Q345R cladded plates significantly alters the subsequent weld thermal cycle and modifies the local interfacial microstructure. Combined electron backscatter diffraction (EBSD) and microscopy analysis demonstrates that deformation twinning, martensitic transformation, and defect initiation are concentrated at the trimaterial junction,

Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

steel research international, EarlyView.
High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...

A Thermal‐Dependent Conductivity Coating for Surface Charge and Electric Field Mitigation Under Electrothermal Coupling Field

High Voltage, EarlyView.
ABSTRACT The problem of gas–solid interface charge accumulation is an important reason for distorting the surface electric field and then inducing surface discharge. The temperature gradient distribution formed on the spacer during the operation of a gas‐insulated transmission line (GIL) will aggravate the surface charge accumulation, further ...

Contextualized Metabolic Modelling Revealed Factors Affecting Isoflavone Accumulation in Soybean Seeds

Plant, Cell &Environment, Volume 49, Issue 7, Page 3543-3559, July 2026.
ABSTRACT Isoflavones, secondary metabolites with numerous health benefits, are predominantly found in legume seeds, especially soybean; however, their contents in domesticated soybean seeds are highly variable. Wild soybeans are known for higher seed isoflavone contents than cultivars. Here we used experimental and modelling approaches on wild soybean (

A combined EBSD/nanoindentation study of dislocation density gradients near grain boundaries in a ferritic steel

, 2022
Microstructural internal lengths play an important role on the local and macroscopic mechanical behaviors of steels. In this study, the dislocation density gradients near grain boundaries in a ferritic steel are investigated using SEM/EBSD together with ...
