Abstract

The characteristics of the initial structural state and phase composition of industrial alloy 1933 are determined. The specific proportion of low-angle boundaries and high-angle boundaries is determined. The mechanism of superplastic deformation of aluminum alloy 1933 with a bimodal structure is considered. In the investigation of the deformation relief the fibrous structures are found, indirectly confirming the presence of a liquid phase during the mechanical tests. The effect of the inclusions of liquid phase, localized at the grain boundaries, on the implementation of deformation and accommodative mechanisms developing during their superplastic flow is analyzed.
