Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Crystallization and Processing of SOFC Sealing Glasses [PDF]

, 2010
The crystallization processes that occur in alkaline earth silicate glasses designed for sealing solid oxide fuel cells (SOFC) have been investigated using differential thermal analysis (DTA) and hot-stage microscopy (HSM).

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Leakage analysis of gasketed flange joints under combined internap pressure and thermal loading [PDF]

, 2011
Leakage in Gasketed Flanged Joints (GFJs) have always been a great problem for the process industry. The sealing performance of a GFJ depends on its installation and applied loading conditions.

THE EFFECTIVENESS OF THE EUROPEAN UNION SEAL REGIME ON THE SEAL HUNT TRADITION

Jurnal Pena Wimaya
This study evaluates the effectiveness of the European Union Seal Regime (EUSR) in addressing seal hunting practices in Sweden and Finland, against the backdrop of growing attention to animal welfare and environmental sustainability. Using a descriptive qualitative approach, the study relies on literature review and official document analysis.

Optimization of the Production of Rubber Compounds Using Mathematical Models

Advanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

Advanced Engineering Materials, EarlyView.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.
