Abstract

Microstructure and mechanical properties of ultrafine grained (UFG) Cu processed by multiple isothermal forging (MIF) are studied and compared to those after processing by equal channel angular pressing (ECAP). It is shown that when the final temperature of MIF and the temperature of ECAP are the same, similar microstructures and mechanical properties are obtained in this material. While MIF allows for obtaining reasonably small grain sizes in the submicrometer range in large scale samples, ECAP allows for processing smaller grain sizes in smaller samples.
