Tailored Hardening and Isothermal Bainitizing of Additively Manufactured Nitrogen‐Enhanced Martensitic Chromium Steel

steel research international, EarlyView.
Tailored heat treatments transform additively manufactured high‐nitrogen martensitic Cr steel from austenitic as‐built condition to high‐hardness states. Isothermal bainitizing at 250°C generates an ultrafine nanostructure and achieves higher hardness than conventional hardening and tempering, highlighting a promising postprocessing route for laser ...

Experimental and Computational Investigation of Slag–Refractory Interactions Under Conditions Relevant to Hydrogen Plasma Smelting Reduction

steel research international, EarlyView.
This study investigates how slag interacts with magnesia–carbon (MgO–C) refractories under conditions relevant to hydrogen plasma smelting reduction. High‐temperature refractory wear tests are combined with thermodynamic modeling to examine refractory dissolution into slag and slag infiltration into the refractory.

Investigation of Serrated Flow in Intercritically Annealed Medium Manganese Steel by In Situ Synchrotron X‐Ray Diffraction

steel research international, EarlyView.
Serrations and stepwise austenite phase transformation were observed in cold‐rolled and annealed medium manganese steels. By in situ XRD experiments, these two phenomena were studied simultaneously. The results show that DSA leads to the creation of PLC bands and load drops in the specimen.

Isothermal Reduction Behavior and Microstructural Evolution of Iron Ore Sinter Under Simulated Radial Blast Furnace Gas Atmospheres With Hydrogen Injection

steel research international, EarlyView.
Commercial iron ore sinter is reduced isothermally under operation‐derived radial blast furnace gas atmospheres with and without 20 kg H2/tHM injection. Hydrogen improves reduction at 900–1100 °C, whereas at 700 °C the high H2O content limits the wüstite‐to‐iron driving force.

Multifaceted Behavior and Versatility Features of Ferritic Stainless Steels, Part II: Investigating Electromagnetic, Mechanical, and Corrosion Behavior

steel research international, EarlyView.
This review's second part details the mechanical, corrosion, and electromagnetic behaviors of FSSs. It integrates the foundational microstructure (texture/defects/precipitates) and processing effects from Part I to establish and analyze complex property–property interrelationships critical for high‐performance applications.
