Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The inherent brittleness of hardmetals stems from the rigid covalent bond in the ceramic matrix and the sharp ceramic/metal interface, which restricts the nucleation and motion of dislocations. In this study, a novel strategy is proposed to activate significant dislocation behaviors in the WC matrix by employing a non‐equiatomic CoNiFeCr ...

Enriched model categories and an application to additive endomorphism spectra
, 2007 We define the notion of an additive model category, and we prove that any additive, stable, combinatorial model category has a natural enrichment over symmetric spectra based on simplicial abelian groups.

Density-based crystal plasticity : from the discrete to the continuum
, 2016 Because of the enormous range of time and space scales involved in dislocation dynamics, plastic modeling at macroscale requires a continuous formulation.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Laser powder bed fusion (LPBF) can fabricate high‐entropy alloys (HEAs) with refined microstructure and enhanced mechanical properties. However, the deformation and fatigue mechanisms of Al‐containing HEAs produced by LPBF remain unclear. In this work, we systematically investigate the tensile properties, deformation mechanisms, and high‐cycle

Journal of Field Robotics, Volume 43, Issue 3, Page 1884-1904, May 2026.ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.

steel research international, Volume 97, Issue 5, Page 2672-2692, May 2026.This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.

Intrinsic Hardness Evolution and Indentation Size Effect Modeling in Cu/Co Doped ZnO, TiO2, and SnO2
Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.ABSTRACT Metal oxides such as ZnO, TiO2, and SnO2 are widely used in structural and functional applications; however, their micromechanical performance is often limited by pronounced indentation size effects and surface‐related deformation behavior.
