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.

Quantitative effects of hydro-dynamic parameters on abrasion extent aggregates by overland flow
Shui kexue jinzhan, 2012 The aggregate is the fundamental structural unit of a soil.The destruction of a soil aggregate that is transported by overland flow may significantly affect the surface runoff and permeability of soils,sediment content and the general erosion intensity ...

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.

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

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.

Evaluation of Slip Effects in the Capillary Flow of Foams
Applied Rheology, 1999 Foams have been prepared from water added with a surfactant (Sodium-Dodecyl-Sulfate, SDS) and a polymer (Poly-Ethylene-Oxide, PEO) at different concentrations. This work was devoted to a study of the flow properties of the foams.

Wave friction factor rediscovered
Geo-Marine Letters, 2011 The wave friction factor is commonly expressed as a function of the horizontal water particle semi-excursion (A wb) at the top of the boundary layer. A wb, in turn, is normally derived from linear wave theory by $$ \frac{{{U_{\text{wb}}}{T_{\text{w}
