Utilization of Non‐Metallic Inclusion to Induce Intragranular Acicular Ferrite Formation Contributing to “Oxide Metallurgy”: Effect of Ti/Al Content on the Microstructure Evolution

open access: yessteel research international, EarlyView.
Fine size inclusion can serve as the effective nucleation site to induce the formation of optimal microstructure, i.e. intragranular acicular ferrite (IAF). Here, the low‐alloy steels with different amounts of Ti and Al contents are prepared, and the inclusion characteristics are quantitatively investigated.

Investigation on Crystallization of CaO‐Al2O3‐B2O3‐BaO Slag Using Differential Scanning Calorimeter and In Situ High‐Temperature Raman Spectroscopy

open access: yessteel research international, EarlyView.
The crystallization of CaO‐Al2O3‐B2O3‐BaO glassy slags was investigated by multiple research techniques. The partial replacement of calcium oxide by barium oxide inhibits the crystallization ability of slag, which contributes to the development of “nonreactive” mold fluxes for high‐aluminum advanced steel continuous casting.

Influence of Steel Recycling on Phase Transformation in Medium‐Manganese Third‐Generation Advanced High‐Strength Steels

open access: yessteel research international, EarlyView.
On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.

Recycling‐Induced Copper Contamination of a 42CrMo4 Quench and Tempering Steel—Scaling and Susceptibility to Hot Shortness

open access: yessteel research international, EarlyView.
In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can

Power‐to‐X Processes with Synthetic Iron Oxides

open access: yessteel research international, EarlyView.
Iron oxide redox cycling connects electrolytic hydrogen production and storage, enabling synthesis gas generation for synthetic hydrocarbons. Integrating H2/CO2 cycles offers carbon‐neutral energy storage and industrial applications, especially in commodity chemical industries. An aluminous‐rich binder stabilizes a sample over 20 H2/CO2 cycles, without
