| Effect of equal-channel angular pressing (ECAP) on deformation behavior of an Al.6%Mg.0.5%Mn.0.2%Sc.0.07%Zr (in weight %) alloy denoted as 1570 was considered. The structural changes during deformation were characterized by the elongation of initial grains towards the axis of ECAP and the development of new fine grains. The fraction of fine grains increased with increasing the strain. The ECAP resulted in significant strengthening. The yield strength approached 480 MPa in the specimen processed to ∼8, whereas that in the initial state is 250 MPa. The relationship between the deformation microstructure and the tensile behavior is discussed. |
