dc.description.abstract	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. An Arrhenius-type constitutive equation is used to describe the constitutive behavior of the hot rolled 4343/4A60 aluminum alloy with the thermal deformation activation energy Q of 118.48 kJ/mol. 4A60 aluminum alloy microstructure is studied using the optical microscope to investigate the dynamic recrystallization. It is revealed that with the temperature between 573 and 623 K the dynamic recovery has an effect on modeling the microstructure evolution of 4A60 aluminum alloy. It has been also concluded that the dynamic recovery is the sole softening mechanism of 4343/4A60 composite.	uk_UA
