摘要: For the first time, plastic deformation characteristics of cross-equal channel pressing (cross-ECAP), a modified equal angular pressing, using cross-shaped instead conventional l-shaped channel, was analyzed by finite element analysis. The in cross-ECAP is more complicated and strain induced much severe than that ECAP. However, localized central linear region workpiece very small developed edge regions, which good agreement with experimental results literature showing nonuniformity microstructure hardness distribution. load requirements are higher comparison to ECAP T-ECAP processes.Copyright © 2008 Elsevier B.V
