Microstructural and mechanical characterization in 7075 aluminum alloy reinforced by silver nanoparticles dispersion

Mechanical and Corrosion Behavior of Al7075 (Hybrid) Metal Matrix Composites by Two Step Stir Casting Process

“…Kalkanli and Yilmaz (2008) prepared Al7075/SiC composites by squeeze casting method and concluded 10 wt.% SiC reinforced composites showed the best hardness, tensile strength and flexural strength in both as cast and heat treated conditions. Flores-Campos et al (2010) fabricated the Al7075 composites with carbon-coated silver nanoparticles and concluded that Vickers micro hardness (HVN) values were higher at higher Ag-CNP contents. Baradeswaran and Elaya Perumal (2014) developed the Al7075 hybrid metal matrix composite through stir casting method.…”

Mechanical properties of aluminum 7075 – Silver nanoparticles powder composite and its relationship with the powder particle size

“…The silver nanoparticles effect over in the particle size is due to (i) silver nanoparticles acts as a process control agent (PCA) [10], refining the particle size during the milling process, and (ii) that silver nanoparticles acts as a solid lubricant during the plastic deformation in the milling process [11], generating in this way, particles with smaller sizes, and reaching a steady state between the fracture and welding mechanisms of the particles at shorter milling times.

Wear resistance analysis of the aluminum 7075 alloy and the nanostructured aluminum 7075 - silver nanoparticles composites

“…The milling times selected were 0, 5, 10 and 15 h. The total milling load was 10 g and the milling ball-to-powder weight ratio was set at 4 to 1, the SPEX vials and milling media were made of hard steel. To avoid oxidation during milling, all runs were done under argon atmosphere, 0.25 ml of methanol as a process control agent (PCA) was used in all experiments [11]. Milling products were cold compacted in steel die with 4 cm diameter.…”
