| Abstract: |
| Accumulative roll-bonding process (ARB) is a well known severe plastic deformation’ technique for production of the ultrafine grained, nanostructured and nanocomposite materials in the form of sheets. In the present study, 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 mechanical properties, tribological properties and wear resistance of produced nanocomposites were investigated. The wear tests by abrasion were performed in a pin- on-disc tribometer. Results show that by increasing ARB cycles and the amount of nano powders, the friction coefficient decreases. |
