Analysis of influencing factors on 3D time domain induced polarization responses in metallic ore exploration 3D time domain induced polarization responses in metallic ore exploration

Open Geosciences
The time-domain induced polarization (TDIP) method is widely used in mineral exploration, particularly for sulfide metallic ores that exhibit strong polarization characteristics. By measuring the voltage after the current is switched off, TDIP can enable

Modeling Dislocation Cutting of γ′ Precipitates in Ni‐Base Superalloys: Linking Atomistic and Dislocation Dynamics Simulations

Advanced Engineering Materials, EarlyView.
Dislocation cutting of γ′ precipitates in Ni‐based superalloys is investigated by linking atomistic simulations with discrete dislocation dynamics. The critical cutting stress is shown to be governed by the antiphase boundary energy, while line tension effects promote edge‐preferred cutting.

Constraining the Pulsar 3D Velocity Distribution: The Impact of Spin–Velocity Alignment

The Astrophysical Journal
Quantifying the natal kick distribution of pulsars is essential for understanding supernova physics and binary evolution, yet measurements are historically limited by the lack of radial velocity data.

Advanced Electron Microscopy and Microcomputed Tomography Analysis of Single‐Crystal Ni‐Base Superalloys After Short‐Term Multiaxial Creep

Advanced Engineering Materials, EarlyView.
This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Forward Modeling of First Order Pure qP Wave Equation in Tilted Transverse Isotropy Media

CT Lilun yu yingyong yanjiu
Reverse time migration (RTM) is a core technique for seismic imaging in complex structures. A key challenge in anisotropic RTM is constructing a pure qP-wave equation free of pseudo-shear-wave artifacts.
