Temperature-dependent deformation and fracture properties of low-carbon martensitic steel in different stress states

Journal of Materials Research and Technology, 2023
The temperature-dependent ductile-brittle transition (DBT) in low-carbon martensitic steel is investigated in different stress states. To capture the effects of the stress state, tensile tests have been performed with flat specimens and three-point ...

In Situ Tailoring of FCC Ductile Phases for High‐Strength Wear‐Resistant Crack‐Free W‐Based Metallic Coatings

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Tungsten is inherently brittle and particularly prone to thermal stress concentration and crack formation during additive manufacturing processes such as laser cladding, which severely limits its engineering applications as a coating material. To address this issue, this study proposes an in situ toughening strategy involving the introduction ...

Machine Learning Applied to High Entropy Alloys under Irradiation

Advanced Engineering Materials, Volume 27, Issue 23, December 2025.
Designing alloys for extreme environments demands fast, trustworthy prediction. This review charts how machine learning—especially machine‐learned interatomic potentials and predictive models based on experiment‐informed datasets—captures the complexity of high‐entropy alloys in extreme environments, predicts phase formation, mechanical properties, and

Development of a micro-scale Y–Zr–O oxide-dispersion-strengthened steel fabricated via vacuum induction melting and electro-slag remelting

Nuclear Engineering and Technology, 2019
In this paper, the CLAM steel strengthened by micro-scale Y–Zr–O was prepared by vacuum induction melting followed by electroslag remelting (VIM-ESR). Yttrium (Y) and zirconium (Zr) were easy to aggregates into massive yttrium-zirconium-rich inclusions ...
