Despite increased hardness, elevated tramp element concentrations in a ferritic‐pearlitic low‐carbon steel lead to enhanced toughness accompanied by a more homogeneous and finer ferritic microstructure. Atom probe tomography reveals pronounced segregation of some tramp elements at grain boundaries and ferrite–cementite interfaces, together with ...

At 800 °C, hematite pellets containing 0.9 wt% CaO reduce in hydrogen at rates 1.2–1.4 times those of pure pellets. The inward‐moving reaction front supports a topochemical description, and FeO‐to‐Fe kinetics are consistent with mixed control by interfacial reaction and intrapellet diffusion.
