Underestimation of Planetary Contraction Due To Obscuration by Surface Roughness: The Case of Mercury

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Estimating Mercury's radial contraction is key to understanding the planet's geodynamic evolution. Contraction has been inferred from mapped shortening structures, whose heterogeneous distribution contradicts the isotropic contraction expected from global cooling.

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

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
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.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
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.

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

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
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 ...
