Abstract :
Accumulative roll-bonding process (ARB) is an important severe plastic deformation technique for
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 Al/SiO2 nanocomposites by using Aluminum 1050 alloy sheets
and nano sized SiO2 particles, at ambient temperature. After 8 cycles of ARB process, the tribological properties and
wear resistance of produced 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 friction
coefficient of produced nanocomposites decreases.
