High‐Entropy Alloy Design Toward Cobalt Substitution for High Hardness and Low Wear Rate Using X–Cr–Fe–Mn–Ni System

Advanced Engineering Materials, EarlyView.
This study explores the replacement of cobalt using the high‐entropy alloy design strategy for wear‐resistant components operating at high temperatures. Starting from the Cantor alloy, cobalt is substituted with Cu, Al, V, or Mo. Metallurgical and tribological analyses reveal that aluminum, vanadium, and molybdenum effectively strengthen the developed ...

Scaling Behaviour and Complexity of the Portevin-Le Chatelier Effect

, 2006
The plastic deformation of dilute alloys is often accompanied by plastic instabilities due to dynamic strain aging and dislocation interaction. The repeated breakaway of dislocations from and their recapture by solute atoms leads to stress serrations and

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 ...
