Critical conditions and grain growth model for dynamic recrystallization of Cu-Ni-Si alloy
Results in Physics, 2019 Hot compression tests of Cu-Ni-Si alloy with high Ni and Si contents were performed at the deformation temperatures of 750–950 °C, and the strain rates of 0.01–10 s−1 on a Gleeble-3800 thermo-mechanical simulator.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

παÏακοπὰ, bad coin in Aeschylus
Humanitas, 2021 El v.223 de Agamenón de Esquilo trata un tema central en la obra, la cadena de errores en un mismo linaje, y el término parakopa interpretado en su significado literal, que está relacionado con la acuñación de moneda, aporta un significado adicional que se va desarrollando a lo largo de la obra.

Advanced Engineering Materials, EarlyView.Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Observation of the Ïð3686ß decays into Σ+ Σ - Ï and Σ+ Σ - Ï
, 2023 Based on (2712.4 +/- 14.3) x 106 events recorded at the psi(3686) nominal mass collected with the BESIII detector operating at the BEPCII collider, the psi(3686) -> E +/- E over bar -omega and E +/- E over bar -phi decays are observed for the first time with statistical significances of 13.8 sigma and 7.6 sigma, respectively.

Characterizations Of Upper And Lower (Α, Β, Θ, Δ, I)-Continuous Multifunctions
, 2021 Let (X, τ ) and (Y, σ) be topological spaces in which no separation axioms are assumed, unless explicitly stated and if I is an ideal on X. Given a multifunction F : (X, τ ) → (Y, σ), α, β operators on (X, τ ), θ, δ operators on (Y, σ) and I a proper ...

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

European Journal of Pure and Applied Mathematics, 2022 In this paper, we extend the concept of β-absorbing submodules to φ-β-absorbingsubmodules over a commutative ring with nonzero identity which is a generalization of 2-absorbing submodules. Let S(M) be the set of all submodules of M and φ : S(M) → S(M)∪{∅} be a function.

Advanced Engineering Materials, EarlyView.Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...
