Abstract: 

Accumulative roll-bonding process (ARB) is an important severe plastic defbrmation technique jiJr production of the ultrafine grained, nanostructured and nanocomposite materials in the form of plates and sheets. In the present work, this process used for manufacturing A1/SiO2 nanocomposites by using Aluminum 1050 alloy sheets and nano sized Sio2 particles, at ambient temperature. After 8 Lycles of ARB process, the tribological properties and wear resistance ofproduced nanocomposites were investigated. The wear tests by abrasion were performed in a pin­on-disc tribometer. Results show that by increasing ARB cycles and the amount of nano powders, the Fiction coefficient of produced nanocomposites decreases.
