Electrochemical and Surface Insights Into X12CrMoWVNbN10‐1‐1 Steel Corrosion in Chloride Solutions at Variable pH

Materials and Corrosion, Volume 77, Issue 4, Page 518-528, April 2026.
The corrosion performance of X12CrMoWVNbN10‐1‐1 steel in chloride environments dramatically depends on pH. Acidic conditions trigger intense surface degradation, whereas neutral and alkaline media foster the formation of a compact and stable passive film, drastically reducing both general and localized corrosion.

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, Volume 97, Issue 3, Page 1201-1225, March 2026.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

With or without you: Family and Career‐Work in a Demanding and Precarious Profession

Journal of Management Studies, Volume 62, Issue 8, Page 3386-3424, December 2025.
Abstract Family arrangements are crucial to people’s abilities to meet the high demands of professional careers; but most scholarship has examined stable, highly remunerated professions. To understand the relationship between career and family within the increasing number of precarious professions, we analyse interviews with 102 journalists.

Predictive Modeling of Activated Tungsten Inert Gas Welding in Grade 91 Steel Using Finite Element Method and Experimental Techniques

steel research international, Volume 96, Issue 11, Page 266-275, November 2025.
This study analyzes the thermal and mechanical behavior of activated tungsten inert gas welding on 4 mm‐thick Grade 91 steel, widely used in high‐temperature applications. Using a combined heat source model, the research predicts weld distortion and residual stress, validated through experiments.
