Constitutive Behavior of 4343/4A60 Aluminum Alloy at Multi-Pass Hot Deformation
Hot roll bonding of 4343/4A60 aluminum alloy has been performed in the Gleeble-3500 thermal simulator. The bonding process constitutive behavior has been analyzed. The results show that the peak flow stress decreases with the increase of the deformation temperature and the decrease of strain rates....
