초록

Much research efforts have been made on the equal channel angular pressing (ECAP) which produces ultra-fine grains. Along with the experiments, the finite element method has been widely employed to investigate the deformation behavior of specimen during ECAP and the effect of process parameters of ECAP. In this paper, sectional shape change has been investigated during ECAP with the pure-Zr, Zr-702 by using three-dimensional finite element analysis. The results have been compared with experimental results.
