Equal channel angular pressing (ECAP) has been employed to produce materials with ultra-fine grains that have<br/> high strength and high corrosion resistance properties. In order to obtain super plastic deformation during ECAP, multipass<br/> angular pressing is frequently employed. In this paper, three-dimensional finite element analyses have been<br/> performed to investigate the deformation behavior of pure-Zr specimen and the effects of process parameters for equal<br/> channel multi-angular pressing (ECMAP) process. The results have been compared with some experimental results
