Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

The influence of platinum washing-out time on its recovery from used auto catalytic converters

Metalurgija, 2014
The used catalytic converters contain small amounts of precious metals. Recovery of these metals is essential for environmental and economic reasons. This work presents a method of Platinum Group Metals (PGM) recovery from auto catalytic converters in ...

Electroluminescent Liquid Metal Marbles for Reconfigurable Multi‐Color Display

Advanced Science
Conventional display technologies rely on rigid architectures, limiting their adaptability for reconfigurable systems. Plasma discharge, as a field‐driven excitation method, offers great opportunities for visual interfaces, yet integrating it into ...

Investigation of Thermo‐Chemical Processes in Commercial MgO‐C Refractory Bricks With and Without MgO‐C Recyclate at Elevated Temperatures

Advanced Engineering Materials, EarlyView.
This study investigates thermo‐chemical processes during high‐temperature testing of two commercial MgO‐C brick grades, one containing 47.5 wt.% MgO‐C recyclate. Using ETV, DTA/TG‐MS, XRD, and SEM/EDS/EBSD, mechanisms such as carbothermal reduction of magnesia, impurity incorporation into the secondary MgO surface layer, and calcium‐rich phase ...

Hydrogen Adsorption on Solid and Liquid Surfaces of Ga–Sn and Ga–In

Advanced Materials Interfaces
Dynamic liquid metal catalysts have remarkable activity and selectivity toward certain reactions, such as carbon dioxide reduction. The surface hydrogen coverage may play a role in this, including controlling competing reactions such as hydrogen ...

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

Advanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

NANOSTRUCTURAL PROCESSES OF MELTING, CRYSTALLIZATION AND MODIFYINGS OF METALS

Литьë и металлургия, 2015
It is shown that melting, crystallization and modifying of metals are difficult nanostructural processes. The nanocrystals and atoms of metals, the centers of crystallization of dendrites, surface-active elements, gases modifying elements, poorly soluble
