Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

Advanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Friction stir processing of Al–CNT composites [PDF]

Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications, 2016
Friction stir processing (FSP) is a solid-state process with the ability to refine grain sizes and uniformly disperse particles to improve the mechanical properties of the base material. In this study, FSP was performed on AA6061-T6 with and without additions of multi-walled CNTs.

Knowledge discovery for friction stir welding via data driven approaches: Part 1 – correlation analyses of internal process variables and weld quality [PDF]

, 2012
For a comprehensive understanding towards Friction Stir Welding (FSW) which would lead to a unified approach that embodies materials other than aluminium, such as titanium and steel, it is crucial to identify the intricate correlations between the ...

Pickering‐Engineered Microparticles for Magnetically Guided Motion and Light‐Triggered Catalysis

Advanced Functional Materials, EarlyView.
Magnetically responsive wax microparticles stabilized by hematite cubes through the Pickering emulsification strategy are developed, showing controlled size, motion, and light‐activated catalytic activity. Annealing under a magnetic field enhances their mobility and steering.
