Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Enhanced Binary Cuckoo Search With Frequent Values and Rough Set Theory for Feature Selection

IEEE Access, 2021
Redundant and irrelevant features in datasets decrease classification accuracy, and increase computational time of classification algorithms, overfitting problem and complexity of the underlying classification model.

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

Advanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

FISCAL DISCIPLINE WITHIN THE EU: COMPARATIVE ANALYSIS [PDF]

Annals of the University of Petrosani: Economics, 2013
This paper focuses on the analysis of the convergence indicators relative to fiscal area in the EU; subsequent to a description of the main peculiarities of the convergence criteria, the reseach develops a critical analysis on a comparative perspective ...

ISSUES REGARDING THE NOMINAL CONVERGENCE CRITERIA FOR JOINING THE EURO AREA [PDF]

Annals of the University of Petrosani: Economics, 2020
Romania, a member state of the European Union, has committed itself to adopting the euro under the Treaty on the Functioning of the European Union, which means meeting nominal and real convergence criteria, as well as achieving parameters for the ...

Ontology‐Aligned Structuring and Reuse of Multimodal Materials Data and Workflows Toward Automatic Reproduction

Advanced Engineering Materials, EarlyView.
Reproduction of stacking fault energy calculations from literature with a semi‐automated large language model‐assisted extraction procedure: extraction of simulation protocol, atomistic structures, computational parameters, and reported results, ontology alignment, knowledge graph construction and, finally, recomputation forvalidation.

THE COSTS AND BENEFITS OF ROMANIA'S ADERATION TO THE EURO ZONE AND ADOPTION OF THE UNIQUE CURRENCY [PDF]

Annals of the University of Oradea: Economic Science, 2010
The accession to the Economic and Monetary Union, though not a criterion of accessing the European Union, involves the compliance with the convergence criteria of Maastricht: stability of the exchange rate, of interest rates, of the inflation, of the ...

Design and Analysis of Compression–Torsion Coupling Metamaterials Using the Golden Section Method

Advanced Engineering Materials, EarlyView.
A novel compression–torsion metamaterial is engineered using inclined rods and symmetry breaking. To optimize its torsional performance, the golden section method is employed. The mechanical response of the metamaterial is validated through both numerical analysis and experimental validation.

Nominal, Structural and Real Convergence of the EU Candidate Countries’ Economies

SSRN Electronic Journal, 2021
Abstract Despite the significant academic interest in the economic cohesion, the various aspects of convergence and the ways they can be measured still remain theoretically unclear. These are issues of extreme political significance, especially for countries aspiring for EU and euro area membership.

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

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 ...
