Microstructural evolution during equal channel angular extrusion (ECAE) was investigated in a coarse-grained dilute aluminum alloy, Al-3%Cu, at a temperature of 250oC. Scanning electron microscopy (SEM) with electron back scattering diffraction (EBSD) and optical metallography (OM) was used to reveal the structural changes in the alloy deformed up to a strain of ε=12. The microstructural evolution at initial and moderate stages of deformation is characterized by the formation of low angle boundaries and deformation bands with moderate misorientations in grain interiors. With further deformation the number and the misorientation of the deformation bands increase, finally leading to the subdivision of original grains by these bands and then the development of fine grains with an average size of about 6 μm at ε=12. The evolution of deformation bands in initial grain interiors and their role on new grain formation are discussed in detail.

Microstructural evolution of AZ61 magnesium alloy was analyzed after ECAE process. This research focused on the effects of deformation temperature and extrusion passes on microstructure of AZ61 magnesium alloy. The results showed that microstructure have not improved significantly at the lower temperature. Grains can be refined greatly at deformation temperature of 370°C. With an increase of extrusion passes, grains tend to be much refined, which is beneficial to obtaining good property.
