Abstract

The features of a structural state and a deformation relief of matrix aluminum alloy 1933 are investigated. It is determined that the grain boundary sliding is carried out intensively both on the high-angle boundaries of ultrafine grains and the low-angle boundaries of large polygonized grains parallel to the strain axis of the sample. The mechanism of the boundary sliding in alloy 1933 with a bimodal structure is discussed.
Keywordsbimodal structure, grain boundary sliding, high-angle grain boundaries, low-angle grain boundaries, superplasticity
