Cation Diffusion-Mediated Displaced Reaction-Transformation in Green Steelmaking. [PDF]

Adv Sci (Weinh)
The removal of O lattice atoms by environmental H2 at the surface of Fe3O4 results in Fe enrichment, driving the inward diffusion of Fe cations into the bulk. Through hopping between unoccupied and initially occupied sites, cation diffusion triggers a spatially displaced reaction‐transformation and drives subsequent dynamic phase transformations and ...

Review on the Use of Alternative Carbon Sources in EAF Steelmaking

Metals, 2021
Steelmaking in the electric arc furnace (EAF), either scrap-based or based on hydrogen direct reduced iron, will in future contribute substantially to the reduction of CO2 emissions in the iron and steel industry. However, there still will be the need to

A Review of Multi-phase Slag Refining for Dephosphorization in the Steelmaking Process

Frontiers in Materials, 2020
Dephosphorization has always been a challenging task in the steelmaking process. In the traditional studies, CaO-based steelmaking slag was usually treated as a homogeneous liquid phase to analyze the dephosphorization equilibrium between molten slag and

Computational thermodynamics as a tool to study the microstructural evolution of EAF duplex stainless steelmaking slags

, 2012
Computational thermodynamics was used as a tool to study and determine the microstructural evolution of the electrical arc furnace (EAF) slag during and at the end of the refining period in the production of duplex stainless steel.

Physics‐Constrained Constitutive Learning of Rate‐Limiting Timescales for Efficient Hydrogen‐Based Direct Reduction for Green Steel Making

Advanced Science, EarlyView.
A conversion‐resolved constitutive framework is developed for the hydrogen‐based direct reduction of iron oxide pellets. Effective reaction and transport timescales are inferred directly from measured trajectories and mapped against operating conditions, pellet architecture, and composition. The analysis reveals how late‐stage transport control emerges

Unlocking the potential of trace cobalt in Ni-based superalloys: A molecular dynamics study on dislocation behavior and high-temperature stability

Materials & Design
Cobalt (Co) is one of the fastest diffusing elements in Nickel (Ni)-based single crystal superalloys, playing a critical role in stabilizing the γ matrix and γ′ precipitate, and influencing dislocation behavior and deformation mechanisms.
