| Abstract Scope |
Silica in iron ore post challenges for solid-state steelmaking because SiO₂ is highly stable and difficult to reduce or transform under conventional reducing conditions. Instead of treating SiO₂ solely as an undesirable impurity, this work explores its potential role as a reactive oxygen- and silicon-bearing phase during sintering Fe-based powders. Particular attention is given to the coupled effects of carbon-bearing species, reactive additions, and the surrounding Fe matrix on oxygen redistribution, oxide transformation, and alloying behavior. Thermal processing experiments, phase analysis, and microstructural characterization are used to examine how SiO₂-containing phases evolve under different processing conditions. The results are expected to provide insight into silica reduction mechanisms and oxide-derived alloying pathways, supporting strategies to covert residual oxide phases into useful contributors to microstructural design in solid-state processed steels. |
