Microstructure Control and Performance Evolution of Aluminum Alloy 7075 by Nano-Treating

Abstract Nano-treating is a novel concept wherein a low percentage of nanoparticles is used for microstructural control and property tuning in metals and alloys. The nano-treating of AA7075 was investigated to control its microstructure and improve its structural stability for high performance. Afte...
