Ultrafast Mechanochemical Synthesis of Plasmonic Transition Metal Nitride Nanoparticles

Small, EarlyView.
Mechanochemistry enables ultrafast synthesis of plasmonic transition metal nitride nanoparticles in minutes rather than hours without external heat supply. The resulting mono‐ and mixed‐metal nitrides display tunable plasmonic absorption, demonstrating a potentially scalable route to refractory plasmonic materials.

Crack growth in castable refractory due to thermal shock fatigue: an acoustoo-ultrasonic study

, 1993
Thermal shock fatigue crack growth in an alumino-silicate castable refractory has been studied using the non-destructive method of acousto-uitrasonic signal analysis.

Analyses of the Deformability and Chemistry of Non‐Metallic Inclusions in QT Steels With Increased Recycling‐Induced Tramp Element Content

steel research international, EarlyView.
This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.

Characterization of Nonmetallic Inclusions in Ce‐Containing Steels at the Submicroscopic Level

steel research international, EarlyView.
Accurate detection of nonmetallic inclusions (NMIs) is crucial for ensuring high standards in steel cleanness and properties. Optimized automated SEM/EDS measurements are required for evaluating Ce‐containing NMIs. This study enhances the characterization of submicroscopic NMI in Ce‐alloyed ultralow‐carbon, high‐manganese, and electrical steels ...

Prospects of Eliminating Fluorspar Consumption in a Sustainable Argon‐Oxygen‐Decarburization Process

steel research international, EarlyView.
This study aims at identifying pathways for eliminating fluorspar consumption in the argon‐oxygen‐decarburization (AOD) process. Thermodynamic calculations suggest the feasibility of completely replacing fluorspar with alternative fluxes such as Al2O3, Na2O, K2O, and Li2O of suitable amounts.

Hybrid Temperature Modeling for the Ruhrstahl–Heraeus Process: Coupling a Data‐Driven Approach With a Physics‐Based Process Model

steel research international, EarlyView.
A hybrid framework combining a mechanistic tanks‐in‐series model, thermodynamic data, and statistical learning methods was developed for continuous temperature prediction during RH vacuum treatment. The framework accounts for temperature changes caused by alloy additions, O2 blowing via top lance, and heat losses to the surroundings. Validation against
