Deoxidation mechanisms in liquid steel.
… techniques have been employed to investigate the deoxidation kinetics and changes in oxidation product morphology in low carbon steel melts. The techniques have been used to study the deoxidation processes associated with aluminium, titanium, silicon, zirconium and a calcium-aluminium alloy.After …

Deoxidation studies : The interaction of vitreous silica with molten aluminium and systems of aluminium, manganese, iron and silicon.
The interaction of aluminium with silica and silicates isthermodynamically inevitable and leads to reaction effects in many systems. The resultant reactions can continue over a wide temperature range including both liquid and solid state systems such as molten aluminium handling units and the heat …

Oxide inclusion evolution and factors that influence their size and morphology
… composition, and morphology following steel deoxidation were found to depend on the steel conditions during deoxidation, and the method/sequence of deoxidant addition. The oxide size distribution evolved from lognormal to fractal and the distribution shape was quadratic or linear on a log-log …

Development of Stage-I tempered high strength cast steel for ground engaging tools
… practice (N< 80 ppm) along with an effective deoxidation. Size of ground Si-Zr addition controls final ZrN particle size. Good mechanical properties can be obtained if ZrN particle size is limited to 2μm. A high oxygen melt practice gave 35% improvement in notch toughness. A Mn-Si-Mo-V steel …
