Experimental and numerical research of crack propagation process and energy dissipation law of grouting specimens under radial impact load

Frontiers in Earth Science, 2023
Different air pressures are used to conduct an impact test based on the split Hopkinson pressure bar (SHPB) test system to study the crack evolution process and energy dissipation law of the cemented rock under impact load.

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Electrochemical Impedance Spectroscopy Characteristic of Ti-6Al-4V Alloy with and Without Welding under the Different Load Model

International Journal of Electrochemical Science, 2016
Electrochemical impedance spectroscopy (EIS) measurements are performed on a Ti-6Al-4V alloy with and without welding. EIS measurements are always performed simultaneously on two identical specimens: one stressed with a slow strain rate tensile test or a

Influence of crystallographic textures on the hydrogen embrittlement resistance of austenitic stainless steel

Journal of Materials Research and Technology
Hydrogen embrittlement (HE) resistance is a significant concern in austenitic stainless steel (ASS) used for hydrogen transportation and storage. While microstructure-controlled methods to enhance HE resistance have been extensively studied in ferritic ...

Study on hydrogen-induced stress corrosion of 7N01-T4 aluminum alloy for railway vehicles

High Temperature Materials and Processes, 2022
7N01-T4 aluminum alloy is widely applied to high speed train body material attributed to its excellent comprehensive mechanical properties; however, its high sensitivity to hydrogen stress corrosion would seriously restrict its further application.

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.
