چکیده
|
The equal channel angular rolling process was successfully performed on commercial pure copper. after 4 passes of this process, grains with a diameter of about 70-500 nm were formed. the fatigue test results showed that the ultra-fine grained copper represents a longer lifetime under stress-controlled fatigue. to clarify the formation process of surface damage, morphological changes in the fractured surface were monitored by scanning electron microscopy.
