Abstract Rare earth silicates are promising thermal/environmental barrier coatings (T/EBC) materials facing silicon‐based ceramic matrix composite substrates and have attracted much attention due to the severe CMAS (CaO–MgO–Al 2 O 3 –SiO ) corrosion. Understanding mechanism of thermal conductivity oxygen vacancy behavior their corrosion products is crucial evaluate performance in post‐service stage. In this work, as well stability migration behaviors these seven studied using...
Abstract Rare earth silicates are promising environmental/thermal barrier coating (E/TBC) materials facing severe CMAS (CaO‐MgO‐Al 2 O 3 ‐SiO ) corrosion. Previous studies mainly focused on the intrinsic properties of precorrosion coatings, but there were few their corrosion products that play a crucial role in performance coatings postservice stage. In this work, mechanical and thermal nine between lutetium studied using first‐principles calculations. Their differences elastic stiffness...
Failure modes of heat seal properties polymer–aluminum–polymer composite films.
This work offers a method to combine the advantages of thermochromic (TC) and electrochromic (EC) smart windows by synthesizing TC–EC dual-response TiO<sub>2</sub>–VO<sub>2</sub> nanocomposite films.
The surface combination treatments of mechanical polishing + chemical-etching passivation are proposed to reduce the states CdZnTe film, which enhances photoresponse performance CdZnTe-based UV detector.
Controlling the formation behavior of inclusions during solidification is an effective approach to improve purity Ni-based superalloys. In this study, effects microsegregation on in continuous unidirectional (CUS) process were investigated. Three types found revert and CUS solidified K418 alloy: nitrides, oxides SiC, with nitrides as dominant inclusions. With application process, precipitation growth behaviors significantly suppressed by larger cooling rate, refinement microstructure, a...
The heat-seal strength of polymer–metal–polymer laminates, widely used in the packaging industry and more recently for pouch lithium-ion batteries, is a critical factor integrity flexible package structures during service. influences lithium hexafluorophosphate/ethylene carbonate/dimethyl carbonate (LiPF 6 /EC/DMC) electrolyte soaking time storage temperature on were investigated through T-peel testing using universal machine. Sealed multilayer laminates’ their failure modes measured...
Adopting effective routs to control the precipitation and size of nitride inclusions in superalloys during solidification is a very interesting subject for metallurgists. The behavior K418 alloy under continuous unidirectional process was investigated by scanning electron microscopy, ASPEX Explorer, LECO ONH-836. results show that there were two types ingot: TiN complex inclusion Al2O3–TiN. There gradient distributions number density, average max sizes along casting direction, as well...
Metal injection moulding in conjunction with hot isostatic pressing was applied to prepare MIM418 superalloy. Densification behaviour, precipitated phases and tensile properties of the alloy were characterised. Relative density 97.6% is obtained after vacuum sintering at 1240°C, near full dense achieved HIPing. High volume fraction (57%) cuboidal γ’ phase average particle size 0.52 μm precipitates homogeneously γ matrix. Small amount fine carbides 0.22 distribute mainly along grain...
In order to bring new insights the transformation mechanism of intermediate phase and its dependence on processing conditions via trifluoroacetate metal organic deposition (TFA-MOD) method, a series quenching experiments with different annealing temperature atmospheres were designed.
