Simulation Study of Gas Cooling for Aero-Engine Borescope Probes

open access: yesAerospace
After an aero-engine shuts down, the high temperature within the core flow path prevents conventional borescope probes from performing immediate internal inspections due to their limited thermal resistance, thereby constraining rapid turnaround ...

An analytical approach for loca (Loss of coolant accident)

open access: yes, 1982
Soğutucu Kaybı Kazası (SKK) oldukça karmaşık dinamik bir süreçtir. İncelenmesi çoğunlukla, ele alınması külfetli bilgisayar programlarının ilgili verilerle koşulmasını gerektirir. Bu programlar üzerinde egemen olunması birikim ister. Bu sağlansa bile elde olunan sonuçların yer yer, fiziksel mi, yoksa çeşitli bilgisayar cilvelerinden bir demet mi ...

PWR LOSS-OF-COOLANT ACCIDENT CORE MELTDOWN CALCULATIONS

open access: yes, 1957
Results are presented of a study made of the possible extent of zirconium-water reaction and core meltdown following a postulated loss-of-coolant accident in the PWR plant. Zirconium-water chemical reaction and core meltdown occur in the course of the core temperature excursion which could follow a loss- of-coolant if no cooling were provided after an ...

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

The Influence of Field‐Assisted Sintering Technology (FAST) Temperature and Cooling Rate on the Microstructural Evolution in Gamma‐Titanium Aluminide Alloy GE4822

open access: yesAdvanced Engineering Materials, EarlyView.
Controlling the Field Assisted Sintering Technology (FAST) parameters, dwell temperature and cooling rate, significantly influences the microstructural evolution in titanium aluminide GE4822. Significant γ‐lamellar colonies develop only upon cooling through the α‐transus.

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

open access: yesAdvanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...
