Microstructure development and hardening during high pressure torsion of commercially pure aluminium: strain reversal experiments and a dislocation based model

Significance of output:

Strain reversal (changing strain/stress directions) is a phenomenon often occurring in power station and industry manufacturing processing, which has very important influence on service life of engineering components. So far, there has been no attempt to conduct any detailed investigation to determine the influence of strain reversal on strengthening during high pressure torsion processing (HPT). In this study, a new model was created to quantitatively calculate the strength changes of aluminium alloy, which can be used as a guide for industrial deformation processes. This study was a collaborative research with Chinese scientist, supported by both EPSRC and China Scholarship Council.
