Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Influence of Surface Roughness and Temperature on Niobium Cathodic Cage Duplex Treatment Applied to VP20TS Steel

steel research international, EarlyView.
Niobium cathodic cage duplex treatment is applied to VP20TS steel to evaluate the influence of surface roughness and temperature on coating performance. Results show that higher temperatures promote thicker nitride layers and increased microhardness, while finer surface preparation enhances adhesion and wear resistance, revealing optimal conditions for

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 ...

Dimethyl‐, Diethyl‐, and Propylene Carbonates: An Emerging Class of Green Solvents for Organic Synthesis

The Chemical Record, EarlyView.
This review highlights recent advances in the use of organic carbonates, dimethyl carbonate (DMC), diethyl carbonate (DEC), and propylene carbonate (PC), as solvents in organic synthesis. Based on over seventy studies from the past 6 years, it shows their application in different organic reaction types, emphasizing their role in safer and more ...
