Experiments were conducted to evaluate the superplastic properties in three orthogonal directions after processing by equal-channel angular pressing (ECAP). Using an Al-3% Mg-0.2% Sc alloy pressed to a strain of ∼8 through route BC, miniature tensile specimens were cut in the pressing direction perpendicular to the transverse plane and perpendicular to the flow and longitudinal planes. The results show that similar tensile elongations are obtained in each direction. It is concluded there is no significant anisotropy in the superplastic properties after processing by ECAP.
