Thermomechanical Validation of an Additively Manufactured Test Chamber for Sustainable Aviation Fuel Atomization in Jet‐In‐Crossflow Conditions

Macromolecular Symposia, EarlyView.
ABSTRACT This study aims to validate the structural and thermomechanical reliability of an additively manufactured test chamber specifically designed for the experimental investigation of sustainable aviation fuel (SAF) atomization under jet‐in‐crossflow (JICF) conditions representative of gas turbine afterburners. The proposed test chamber is designed

A Comparison of Classical Constitutive Models for High‐Entropy Alloy Behavior: Effects of Medium Strain Rates and Temperature on Plastic Flow

Materials Genome Engineering Advances, EarlyView.
Four constitutive models are evaluated for FeCoNiCr and Al0.6FeCoNiCr HEAs under wide temperature and strain‐rate conditions. The predictive capabilities and limitations of each model are then critically assessed, with particular emphasis on strain rate sensitivity, temperature dependence, and physically unrealistic responses at extreme loading ...

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Enhancement of wear and erosion-corrosion resistance of Inconel 718 alloy by liquid nitriding

Materials Research Express, 2020
Inconel 718 alloy is often used for the oil and gas industry, which usually failed due to the erosion-corrosion of multi-phase flow. In this study, we expect to enhance the wear and erosion-corrosion resistance of Inconel 718 alloy by liquid nitriding ...
