Formation of bimodal grain structures in high purity Al by reversal high pressure torsion
(2011) In Scripta Materialia 64(6). p.498-501- Abstract
Bimodal grain structure was fabricated in a 99.99% purity aluminium by high pressure torsion at ambient temperature in reversal deformation mode at a strain amplitude Δε = 1, strain rate ̇=1.1×10 -1s-1 and hydrostatic pressure P = 5 GPa. Enhanced boundary mobility due to the high purity of the aluminium and homologous temperature coupled with reversal simple shear deformation are found to be responsible for bimodal microstructure formation.
