چکیده مقاله
In this research, five strips, made of Al-7075 in the routes A and C and five strips made of Al-5052
in the route C, were subjected to the equal channel angular rolling (ECAR) process during 5 passes
in order to study the changes of hardness in the ECARed Al-7075-o and 5052 strips. The process of
equal channel angular rolling is one of the severe plastic deformation processes which are used for
strengthening metal sheets. The results of hardness test showed that by increasing the number of
passes, surface hardness and hardness in the direction of thickness for ECARed Al-7075 alloy were
increased 63% and 46% in the route A, respectively and 51% and 30% in the route C respectively.
Also, the hardness in the direction of thickness and surface hardness in Al-5052 alloy were
increased 41% and 64%, respectively.
