Atomic‐Scale Insights Into Tramp Element Segregation and Mechanical Performance of a Low‐Carbon Steel

steel research international, EarlyView.
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 ...

The behavior of manganese in oxygen steelmaking [PDF]

, 2019
The chemical behavior of manganese in oxygen steelmaking is complex because the element is readily oxidized in conditions found in steelmaking, and the stability of its oxide is a function of temperature and slag chemistry.

Hydrogen Reduction of Synthetic Fe2O3 Pellets: The Role of Calcium Oxide in Porosity Evolution and Reduction Kinetics

steel research international, EarlyView.
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.

Hybrid Temperature Modeling for the Ruhrstahl–Heraeus Process: Coupling a Data‐Driven Approach With a Physics‐Based Process Model

steel research international, EarlyView.
A hybrid framework combining a mechanistic tanks‐in‐series model, thermodynamic data, and statistical learning methods was developed for continuous temperature prediction during RH vacuum treatment. The framework accounts for temperature changes caused by alloy additions, O2 blowing via top lance, and heat losses to the surroundings. Validation against

Effect of Hot Rolling Temperature on Oxide Scale Formation, Grain Size, and Pickling of Stainless Steel

steel research international, EarlyView.
The effects of finishing rolling temperature, coiling temperature, and annealing on scale formation and pickling performance are studied. Scale morphology and composition are studied via SEM‐EDS, and pickling performance is studied by evaluating scale residues and mass losses during pickling.

Droplet generation in oxygen steelmaking

, 2009
Droplet generation is a crucial part of the process kinetics of oxygen steelmaking because it contributes to large interfacial area during the blow which in turn affects the mass transfer between metal and slag.
