Paper Title:
Microstructure Evolution after Large Strain Deformation in Al-0.13%Mg
  Abstract

The effect of large strain deformation on microstructural refinement has been intensely investigated by many deformation processes. Two popular processes are equal channel angular extrusion (ECAE) and accumulative roll-bonding (ARB). This work presents the evolution of microstructure in Al-0.13%Mg as a function of von Mises strain for both ECAE and ARB in terms of high and low angle boundary spacing and relative fraction, as well as the stability of the deformed structures after a strain of 10, thereby allowing a direct comparison of the two processes. It is found that microstructural evolution as a function of strain is similar, and that ARB structures after a strain of 10 are more stable than ECAE on annealing.
