Multimodal Data‐Driven Microstructure Characterization

Advanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Concretos refratários engenheirados com expansão controlada para panelas de siderurgia Engineered refractory castables with controlled expansion for molten steel ladles

Cerâmica, 2008
A seleção de revestimentos refratários para a siderurgia é dependente de fatores termodinâmicos e microestruturais. O emprego de óxidos termodinamicamente estáveis, como a alumina e a magnésia, é fundamental para o aumento de vida útil do produto, por ...

Thermodynamic Properties of MgAl₂O₄ Spinel at High Temperatures and High Pressures

Crystals, 2023
Thermodynamic properties of MgAl2O4 spinel are significant in understanding the phase relations of the Earth’s crust and upper mantle, but available values from experimental measurements are limited at ambient pressure conditions to date.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Structural properties of Mn-substituted hercynite

Nukleonika, 2017
In this work spinel series with the general formula Fe1-xMnxAl2O4 (where x = 0, 0.3, 0.5 and 0.7) were synthesized and characterized with respect to their structure and microstructure. X-ray diffractometry (XRD) was used to identify the phase composition

Phase-Pure Epitaxial b-Axis-Oriented Bronze TiO₂ Films

Applied Sciences, 2022
We demonstrate the heteroepitaxial growth of phase-pure bronze-phase TiO2 films using pulsed laser deposition on MgAl2O4 single-crystal substrates. While the growth on cubic substrates with smaller lattice parameters favors the stabilization of an out-of-
