On anisotropy of mechanical properties of aluminum alloys under high temperature deformation

The anisotropy factor assessment under various parameters of thermomechanical loading is estimated by the example of experimental studying deformation and structural parameters of anisotropic Al alloy 1561. It is found that the smallest value of the anisotropy factor corresponds to the formation of equiaxed fine-grained structure formed in the temperature-rate conditions of superplasticity.
