Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Dynamic Analysis for Stair-Climbing of a New-Style Wheelchair Robot
, 2010 In this paper, a wheelchair robot equipped with new-style variable-geometry-tracked mechanism is proposed. Different from general variable-geometry-tracked mechanisms, the key feature of this new-style mechanism is that it can adapt to convex terrain and

Advanced Engineering Materials, EarlyView.This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

The Somaesthetics of Rock Climbing
How can we develop an artistic practice that is relevant and satisfying in terms of mental challenges and physical intensity alike? How can we reach a state in which any human practice can be satisfying in both senses?

Advanced Engineering Materials, EarlyView.Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Isogloss. Open Journal of Romance LinguisticsThis paper explores the correlation between clitic climbing and restructuring. In particular, it offers evidence from Catalan and cross-linguistic data to demonstrate that restructuring is universal and that clitic climbing is a facultative epiphenomenon of restructuring. In this sense, the proposal presented here claims that restructuring verbs select

Advanced Engineering Materials, EarlyView.Mass density governs the protective behavior of oxide layers on nuclear fuel cladding. Ptychographic X‐ray computed tomography measures zirconium oxide grown on Zircaloy‐4 under reactor and autoclave conditions, revealing nearly identical bulk densities of 5.1 ± 0.80 g cm−3.

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.
