title = "Effect of HPT on age-hardening behavior in Cu-added excess Mg-type Al-Mg-Si alloys",
abstract = "Severe plastic deformation (SPD) techniques such as high pressure torsion (HPT) have been extensively researched to achieve. SPD process makes use of the plastic deformation where no change in the cross-sectional dimension of a work piece occurs during straining.In this work, the effect of HPT on aging behavior and microstructure in excess Mg-type Al-Mg-Si alloys including Cu. These alloys were investigated by hardness test and TEM observation. The results show that processing by HPT leads to significant grain refinement with a grain size of ~250nm. Age-hardening phenomenon is observed at 343K and 373K for the Al-Mg-Si alloys with HPT. A few density of dislocation in the crystal grain was observed. The typical needle-shaped precipitates of Al-Mg-Si alloys were not observed in the matrix.",
