| Abstract Scope |
The possibility of producing carbon steels of various grades from the direct reduction of metal oxide feedstocks offers a sustainable alternative to the traditional steelmaking process. In this study, the production of various grades of carbon steel is demonstrated through the reduction, gas carburization, and sintering of metal oxides bound in a polymer network. This work aims to characterize the effects of polymer burnout on the mass transport of reactant gases through brown body specimens. It is presented that the open channels in unsintered powder left from polymer thermolysis allow for a through-thickness homogeneity in reduction and carbon distribution. This is proved via the use of micro-computed tomography (µCT), microhardness testing, and microstructural analysis. This work has implications for applications such as material extrusion, ink-based additive manufacturing, and slip casting. |
