Microstructural Evolution and Mechanical Performance of Plasma‐Assisted Hybrid Friction Stir Welded Dissimilar Aluminum–Copper Joints

Advanced Engineering Materials, EarlyView.
Plasma‐assisted hybrid friction stir welding of dissimilar AlCu joints employs localized plasma preheating to balance heat input and enhance plastic flow. The optimized process reduces axial force by up to 35%, refines the microstructure, and achieves ≈96% joint efficiency.

Mechanically Deposited Wear‐Resistant Amorphous Zr55Cu30Al10Ni5 Coatings

Advanced Engineering Materials, EarlyView.
Mechanically deposited from glassy ribbons, the Zr55Cu30Al10Ni5 amorphous coating formed a hard, continuous layer on AISI 1010 steel, tripling substrate hardness, lowering friction, and reducing wear. Despite its rough surface, it showed friction and wear behavior comparable to the crystalline alloy, highlighting its strong potential as a durable ...

Enhancing Fatigue Performance by Tuning of Residual Stresses in Welded Joints through Nanometallic Multilayer

Advanced Engineering Materials, EarlyView.
This study investigates the fundamental mechanisms of a novel postweld treatment that significantly enhances fatigue performance through engineered residual stress (RS) states. A multiscale approach correlates tensile RS in the nanometallic multilayer coating with corresponding compressive RS in the steel substrate, thereby reducing localized stress ...

Fabrication of Multifunctional FeSi Gyroid Lattice Composites via Additive Manufacturing and Polymer Infiltration

Advanced Engineering Materials, EarlyView.
A two‐step approach combining laser powder bed fusion of FeSi electrical steel with Bakelite infiltration enables the fabrication of multifunctional gyroid lattice composites. The resulting structures exhibit high strength, magnetic anisotropy, and complete polymer infiltration, demonstrating a simple and scalable route toward lightweight, mechanically
