Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines
Advanced Engineering Materials, EarlyView.Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

The impact of community cohesion on youth work: A case study from Oldham
, 2006 Initiated by the 2001 disturbances in Oldham, Burnley and Bradford, 'community cohesion' offers a critique of the apparently negative race relations in many of Britain's towns and cities.

Cohesion and cohesion mechanisms in the composition of texts
Lengua y Sociedad, 2014 En la enseñanza de la redacción y composición de textos, ¿qué enseñar?, ¿para qué enseñar?, ¿cómo enseñar? son preguntas recurrentes que se hacen los docentes de esta área cuando realizan su labor en la universidad. Desde luego, estas interrogantes están relacionadas con la materia que enseñan y las estrategias metodológicas que utilizan. Precisamente,

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.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Local Passion, National Indifference: Implementing Community Cohesion policies in Northern England
The emergence of Community Cohesion (Cantle, 2001) as national policy from 2001 was portrayed as the ‘death of multiculturalism’ in Britain (Kundnani, 2002).

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy
Advanced Engineering Materials, EarlyView.This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

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.
