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.

Dental Microwear Texture Analysis on Radular Teeth

Advanced Materials Interfaces, Volume 13, Issue 19, 6 October 2026.
3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

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

VIEW Medicine, Volume 1, Issue 1, November 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 ...

Synergistic Enhancement of Mechanical and Electrical Properties and Corrosion Resistance of Graphene‐Copper Composites by Accumulative Roll Bonding

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Graphene‐reinforced copper (Gr/Cu) composites have attracted considerable attention because of their potential to achieve a synergistic enhancement of strength, electrical conductivity, and corrosion resistance; however, the poor dispersion of graphene in the Cu matrix remains a key limitation for their further development.
