International Journal of Materials Science and Applications, 2015 Paraffin wax (sulfur and phosphorous free)used as carburizer material for low carbon steels(Steel20, Steel3, and Steel 20x) instead of kerosene. Results show 1) Carburized layer by wax is more depth than in case of kerosene for all the three types of steel, e.g.

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 ...

MICROANALYSE DES JOINTS CARBURE-CARBURE DANS LES COMPOSITES CARBURE DE TUNGSTÈNE-COBALT [PDF]
Le Journal de Physique Colloques, 1984 La concentration en cobalt aux joints de grains carbure-carbure des composites WC-Co a été déterminée par microanalyse X à sélection d'énergie en microscopie électronique à balayage en transmission. Il a été montré que seuls, les joints généraux se caractérisaient par une forte augmentation de la concentration en cobalt. Il est possible d'en déduire la

Effect of carbonization on the mechanical properties of mild steel utilizing oak charcoal as a carbon source [PDF]
Engineering and Technology JournalCarburizing is a process that improves the mechanical properties of low-carbon steel, particularly its surface hardness. Introducing carbon into the steel's surface enhances the creation of a durable and resistant outer layer. The technique is ...

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.The tandem process involves CO2 methanation and CH4 pyrolysis for CNT synthesis. Unreacted CO2 and H2 from methanation oxidize Fe, suppressing CNT growth on Fe‐only catalysts. Incorporation of Mo into Fe/MgO forms Mo2C, which prevents Fe oxidation under CO2/H2 conditions and thereby enables CNT formation.
