steel research international, EarlyView.Strain‐induced NbC precipitation governs hot‐deformation resistance in CrNiMnMoB ultrahigh‐strength steel by suppressing dynamic recrystallization, increasing activation energy, and refining martensitic substructures. The precipitation response is controlled by temperature, supersaturation, and strain rate, with slow deformation promoting extensive NbC

Transferable Hot‐Deformation Flow‐Curve Modeling Across Steels Through Transfer Learning
Materials Genome Engineering Advances, Volume 4, Issue 4, October 2026.We propose a transferable sequence model that moves steel hot‐deformation ML beyond the “one‐case, one‐model” paradigm. Pretrained across compositions/windows and personalized with four extreme‐condition curves, it improves accuracy and robustness in 10‐fold evaluation.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Optimization of resistance spot welding parameters for microalloyed steel sheets
Open Engineering, 2016 The paper presents the results of resistance spot welding of hot-dip galvanized microalloyed steel sheets used in car body production. The spot welds were made with various welding currents and welding time values, but with a constant pressing force of ...

Advanced Energy and Sustainability Research, Volume 7, Issue 9, September 2026.Hydrogen embrittlement proceeds through three distinct mechanisms: localized plasticity, decohesion, and hydride formation, each demanding different experimental evidence across atomic to macroscopic scales. This review maps experimental techniques to their operative mechanism and proposes a multiscale, mechanism‐informed framework linking technique ...

Influence of plasma nitriding pressure on microabrasive wear resistance of a microalloyed steel
Journal of Materials Research and Technology, 2019 Microalloyed steels have been studied not only by the advent of the pre-salt, but also by the continuous search for improvement of their tribological properties.
