Cenozoic Volcanic Provinces and Shallow Asthenospheric Volumes in the Circum‐Mediterranean: Evidence From Magmatic Geochemistry, Seismic Tomography, and Integrated Geophysical‐Petrological Thermochemical Inversion

Geochemistry, Geophysics, Geosystems
We compile an extensive catalog comprising geochemistry and ages of Cenozoic volcanic provinces in the Mediterranean region, distinguishing between three groups according to the geochemistry of magmatic rocks: intraplate (IVP), subduction‐related (SRVP),

Crust and Upper Mantle Structure of the South China Sea and Adjacent Areas From the Joint Inversion of Ambient Noise and Earthquake Surface Wave Dispersions

Geochemistry, Geophysics, Geosystems, 2021
In this study, we built a high‐resolution 3D S‐wave velocity model of the South China Sea (SCS) and adjacent areas by the joint inversion of surface wave dispersions retrieved from ambient noise and earthquake data.

Global mapping of the uppermantle by surface wave tomography

, 1987
Surface wave tomography compliments detailed body wave studies by providing a global framework for the lateral variability of the uppermantle. In particular the method allows one to map the mantle beneath the lithosphere and to discuss the fate of overridden oceanic plates. Midocean ridges appear to extend to at least 400 km. By contrast, the very high

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

基于PyQt5的面波频散曲线成像平台的设计与实现

Dizhen xuebao
面波频散成像在研究地下介质波速结构方面起着重要作用，然而目前公开的面波频散成像工具大多在命令行环境下运行，使用不同种编程语言对数据进行前后处理，对于普通用户而言：① 运行环境的配置难度系数高；② 需要较强的编程能力进行数据加工以及结果展示。为解决上述问题，本文基于PyQt5开发了一款易于部署在Windows 11操作系统上的面波频散曲线成像平台（SWDIT）。SWDIT已集成多种模块，包括半波长法模块、三维面波走时反演模块、三维数据可视化模块，可对用户输入的频散曲线信息进行灵活成像 ...

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Layered Seismic Anisotropy and Tectonics of the Anatolian Plate

Geophysical Research Letters
Anatolian tectonics are associated with slab retreat in the west and gravitational potential energy and continental collision in the east, leading to westward motion of Anatolia relative to Eurasia, partially accommodated on the North and East Anatolian ...

Ontology‐Aligned Structuring and Reuse of Multimodal Materials Data and Workflows Toward Automatic Reproduction

Advanced Engineering Materials, EarlyView.
Reproduction of stacking fault energy calculations from literature with a semi‐automated large language model‐assisted extraction procedure: extraction of simulation protocol, atomistic structures, computational parameters, and reported results, ontology alignment, knowledge graph construction and, finally, recomputation forvalidation.
