خلاصه مقاله:
Accumulative roll bonding (ARB) was used to fabricate the Cu-Zn multilayer and Cu-Zn solid solution. A lamellar structure with the hardness of about 130 VHN was formed after eightARB cycles. Following the suitable heat treatment, a solid solution with a uniform microstructureand hardness of about 57 VHN was produced. The dominant wear mechanism in the ARBprocessed multilayer was found to be delamination and spalling while in the heat-treated samplewas adhesion. The weight loss of the ARBed multilayer was higher due to the occurrence ofspalling and formation of the cracks and cavities during the ARB. On the other hand, the frictioncoefficient and its undulation were lower, which was contributed to the lubricating effect of Znand the higher hardness of the ARB processed multilayer. In the heat-treated sample, the ability ofplastic deformation and the adhesion between the contact surfaces causes the increase in thefriction coefficient and its variation.
