Abstract
Equal-channel angular pressing (ECAP) was conducted on an Al-l%Mg-0.2%Sc alloy using a die having a channel angle (Φ) of 90° but with two different angles, 0° and 90°, for the outer arc of curvature (Ψ). Microstructures were observed by optical microscopy and transmission electron microscopy to examine the effect of Ψ. Tensile tests were also conducted and the ductility was examined for the ECAP samples processed with the two different angles, Ψ=0° and Ψ=90°. It is shown that the microstructure was more homogeneous for Ψ=0° than Ψ=90°. However, larger ductility was obtained for the samples processed with Ψ=90° than Ψ=90°.
