Direct Observation of Matrix‐to‐Precipitate Elemental Diffusion in Severe Plastic Deformation

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Elemental redistribution, particularly the solute exchange between the matrix and precipitates, is a central issue in alloys subjected to severe plastic deformation (SPD). To elucidate this behavior, a nickel–aluminum bronze (NAB) alloy was processed by high‐pressure torsion (HPT), and its microstructural evolution was systematically ...

Strain weakening and superplasticity in a Bi-Sn eutectic alloy processed by high-pressure torsion

, 2014
High-pressure torsion (HPT) was conducted on disks of a Bi-Sn eutectic alloy under a pressure of 6.0 GPa. The microstructural evolution was studied by scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD). Measurements of Vickers

Twin-induced plasticity of an ECAP-processed TWIP steel [PDF]

, 2017
The TWIP steels show high strain hardening rates with high ductility which results in high ultimate tensile strength. This makes their processing by equal channel angular pressing very difficult.

Grain refinement of commercial purity Magnesium processed by Ecap (Equal Channel Angular Pressing)

Materials Research, 2012
Grain refinement in magnesium is evaluated in the present paper. Equal Channel Angular Pressing is used to process commercially pure magnesium. Processing was carried out at 523 K which is lower than the temperature used in other papers on the literature.

Heat transfer modeling in asymmetrical sheet rolling of aluminium alloys with ultra high shear strain

MATEC Web of Conferences, 2016
Asymmetrical sheet rolling is a method of severe plastic deformation (SPD) for production of aluminium alloys with UFG structure. Prediction of sheet temperature during SPD is important.

Thermo‐Chemically Modified Silk Scaffolds Reveal Niche‐Driven Regulation of Hematopoiesis and Fibrosis

Small, Volume 22, Issue 18, 25 March 2026.
We introduce a versatile 3D platform that recreates key physical and biological features of the human bone marrow. By integrating tunable silk biomaterials, stromal cells, and human hematopoietic progenitors, the model captures both healthy and diseased microenvironments, analysis of blood formation, and its disruption in pathological conditions ...

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

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

Advanced Engineering Materials, Volume 28, Issue 4, 18 February 2026.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.
