Abstract

âº The low SFE in Ag caused a very large dislocation density after both ECAP and HPT. âº The minimum grain size achieved by both ECAP and HPT in Ag was about 200Â nm. âº The dislocation density after HPT is three times larger than after ECAP. âº The low SFE in Ag resulted in significant twinning during both ECAP and HPT. âº Twin boundary frequency is also 2-3 times larger after HPT compared to ECAP.
