Microstructure evolution of austenite-to-martensite transformation in low-alloy steel via thermodynamically assisted phase-field method

open access: yesJournal of Materials Research and Technology
The austenite-to-martensite phase transformation plays a crucial part in the microstructure evolution of steel, with the morphology and grain size of martensite being key factors that influence the mechanical properties. This study explores the influence

Transferable Hot‐Deformation Flow‐Curve Modeling Across Steels Through Transfer Learning

open access: yesMaterials 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.

Eutectic Topology Regulates Deformation Pathways Enabling Synergistic Superelasticity and Strength in EBF3‐Fabricated NiTiNb Alloys

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The deformation behavior of NiTiNb shape memory alloys is governed by microstructural heterogeneity, specifically the interconnected topology of the β‐Nb phase. The regulatory role of the eutectic structure in load partitioning and the evolution of deformation mechanisms, particularly in high‐Nb systems, has not been clearly understood.

Lattice‐Defect‐Coordinated Microstructural Continuity and Mechanical Compatibility in LPBF‐Fabricated CoCrNi/316L Bimetallic Structures

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Bimetallic structures fabricated by laser powder bed fusion (LPBF) provide an effective strategy for achieving multifunctional integration, yet interfacial structural continuity and the role of lattice defects remain insufficiently understood.
