Electromagnetic Stirring versus ECAP: Morphological Comparison of Al-Si-Cu Alloys to Make the Microstructural Refinement for Use in SSM Processing

Advances in Materials Science and Engineering, 2016
This work evaluates the morphological evolution at the semisolid state of the Al-4.0wt%Si-2.5wt%Cu alloy produced by direct chill casting under electromagnetic stirring (EMS) and by one equal channel angular pressing (ECAP) pass.

Bioresorbable Scaffolds for Coronary Arteries: Where Do We Stand Today?

VIEW Medicine, Volume 1, Issue 1, August 2026.
Bioresorbable coronary scaffolds are moving from thick strut pitfalls to thinner, stronger, healing‐oriented designs. Integrating advances in materials, guided implantation with preparation, size, and postdilation steps, and resorption aligned to healing, we synthesize clinical evidence and chart a roadmap toward intelligent, transient platforms ...

Heat‐Resistant Copper Alloys for Extreme Thermal Environments: Mechanisms, Architectures, and Design Strategies

cMat, Volume 3, Issue 2, June 2026.
ABSTRACT Copper (Cu) and copper‐based alloys are indispensable in high‐heat‐flux systems, such as aerospace propulsion, fusion reactors, and advanced power electronics, due to their high thermal conductivity and good manufacturability. However, extreme service conditions increasingly demand not only high thermal conductivity but also elevated ...

Impact of geometric factors and shear stress on endothelial function: Hemodynamic insights from human cerebral arterial bifurcations

Physiological Reports, Volume 14, Issue 11, June 2026.
Abstract Vascular inflammation is not a random biological event but rather a process that is strictly regulated by physical forces. While biochemical mediators are well characterized, the local physical mechanisms that predispose specific cerebral vascular sites to inflammation, specifically the geometry of arterial bifurcations, remain ...

Advancing Severe Plastic Deformation for Tubular Samples: Systematic Review and Machine Learning Optimization

MetalMat, Volume 3, Issue 1, March 2026.
This review highlights recent advancements in Severe Plastic Deformation (SPD) techniques tailored for tubular samples. The mechanisms of processing are critically discussed with emphasis on microstructural control and the governing process parameters that enable refinement to ultrafine‐ and nano‐grained structures. Comparative insights into equivalent

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.

Equal-Channel Angular Pressing of NiAl

, 2010
Equal-channel angular pressing (ECAP) was applied to polycrystalline NiAl at temperatures around the brittle-to-ductile transition temperature (BDTT). NiAl rods encapsulated in a steel jacket were ECAP-processed in a die with a channel angle of 120°. The

Inverse Engineering of Mg Alloys Using Guided Oversampling and Semi‐Supervised Learning

Advanced Intelligent Discovery, Volume 2, Issue 1, February 2026.
End‐to‐end design of engineering materials such as Mg alloys must include the properties, structure, and post‐synthesis processing methods. However, this is challenging when destructive mechanical testing is needed to annotate unseen data, and the processing methods for hypothetical alloys are unknown.
