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

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.

Atomically Revealing Bulk Point Defect Dynamics in Hydrogen‐Driven γ‐Fe2O3 → Fe3O4 → FeO Transformation

Advanced Functional Materials, EarlyView.
In situ TEM uncovers the atomic‐scale mechanisms underlying hydrogen‐driven γ‐Fe2O3→Fe3O4→FeO reduction. In γ‐Fe2O3, oxygen vacancies cluster around intrinsic Fe vacancies, leading to nanopore formation, whereas in Fe3O4, vacancy aggregation is suppressed, preserving a dense structure.
