Oxide Scale Morphology of Carbon Steels Under Novel Reheating Conditions

steel research international, EarlyView.
This study focuses on the changes in oxide scale morphology formed under simulated hydrogen and oxy‐fuel reheating gas atmospheres in comparison to natural gas‐air reheating. Several different properties were analyzed, such as pore structure, ratios of iron oxides, adhesion, and distribution of alloying elements.

Stigma Management within and between Levels

Journal of Management Studies, EarlyView.
Abstract We respond to recent calls to connect our understanding of stigma across and between levels of analysis by investigating how stigma management strategies to the same stigma vary and relate in nested industry, organizational, and individual actors.

Practice and Exploration on Raising Scrap Ration during Steelmaking with V-Ti Hot Metal

Teshugang, 2018
Xichang company's steelmaking plant adopts duplex steelmaking process which includes vanadiuniextrac- ting and steelmaking. In the process, vanadium extracting reduces the total heat. After vanadium extracting, the product is called semi-steel.

Between Order and Confusion: Clearing up Structural Misconceptions in Carbon Materials Nomenclature

Angewandte Chemie International Edition, Volume 65, Issue 11, 9 March 2026.
Despite the versatile use of carbon materials, inconsistent terminology and inadequate characterization – especially regarding graphene structures based on sp2‐hybridized carbon atoms – often cause confusion. This perspective clarifies terms like graphite, graphitic carbon, non‐graphitic carbon, and amorphous carbon by aligning IUPAC definitions with X‐

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

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
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.
