EFFECT OF ECAP ROUTES ON STRAIN TO M1 COPPER PLATE

Abstract

This study utilizes 3D simulations to assess the influence of four different ECAP
routes on the mean strain and strain homogeneity on the M1 copper plate. After six
passes, the simulation results significantly improved the mean strain and strain
homogeneity. The mean plastic strain increases significantly when applied along route
BC, while it decreases most along route A. The strain homogeneity is best when used
along route A and poor when applied along route C throughout the entire volume.
However, when examining a cross-section 20mm away from the sample head, which
represents the features in the center of the sample, it is clear that applying through
route C leads to a greater degree of uniform deformation than routes BA and BC. The
results showed that route A is suitable for pressing when the entire material is required.
However, routes BA and BC are utilized when a significant mean strain is desired and
only a uniform material section is used.
