Effect of solution cooling methods on properties and residual stress of GH4096 alloy

Journal of Aeronautical Materials, 2022
In order to ensure the main mechanical properties of GH4096 alloy, reduce the internal residual stress of forgings for thin-walled parts and improve the dimensional control accuracy of parts machining, the effect of air cooling (AC), wind cooling (WC ...

Nanotribology at high temperatures [PDF]

Beilstein Journal of Nanotechnology, 2012
Recent molecular dynamics simulation results have increased conceptual understanding of the grazing and the ploughing friction at elevated temperatures, particularly near the substrate’s melting point. In this commentary we address a major constraint concerning its experimental verification.

Electrical Conductivity of Thin Film SrTi_0.8Fe_0.2O_3−δ-Supported Sr_0.98Zr_0.95Y_0.05O_3−δ Electrolyte

Ceramics, 2022
Thin films of Sr0.98Zr0.95Y0.05O3−δ (SZY) electrolyte were grown on porous supporting SrTi0.8Fe0.2O3−δ electrodes by the chemical solution deposition method from a low-viscous solution of inorganic salts. The films were characterized by X-ray diffraction

Low-Vacuum Pyrolysis of YBCO Films by Using Fluorine-Free Metal Organic Chemical Deposition

Crystals, 2022
The preparation of YBCO superconducting films by using metal organic chemical deposition (MOD) involves low-temperature pyrolysis and high-temperature treatment. The former process generally requires the introduction of water vapor and other gases.

Thermal properties of fluoride mixtures near the melting point

Chimica Techno Acta
The thermal diffusivity of LiF-NaF-KF (FLiNaK), NaF-KF and FliNaK-NdF3 mixtures was studied by laser flash method near the melting point. The obtained results demonstrate that the thermal diffusivity of the melts slowly decreases within a certain ...
