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.

Tuning Grain Boundary Carbides via Solute Rare‐Earth Elements to Prevent Intergranular Brittle Fracture

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Carbides strengthen the grain boundaries; nevertheless, excessive carbide precipitates embrittle the grain boundaries of high‐temperature alloys during prolonged service. Here, we provide direct evidence of solute rare‐earth atoms and demonstrate that they can trap vacancies and inhibit interstitial diffusion, restraining carbide precipitation

Development of Microalloyed Intragranular Ferrite Steel With High Strength and Toughness

Teshugang, 2005
The general chemical compositions of microalloyed intragranular ferrite steels are 0.2~0.4C,0.2～0.8Si, 1.0~1.7Mn,0.05～0. 15V. It is a main measure to increase the strength and toughness of ferite-pearlite microalloyed steel using recrystallized forging ...

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.

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

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 ...

Multiscale Experimental Techniques for Evaluating Hydrogen Resistance in Structural Alloys for Energy Systems

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 ...
