This study investigates the deformation behavior of commercially pure aluminum using
finite element analysis, focusing on the combined equal channel angular pressing (ECAP)
and extrusion process. The objective is to analyze the effects of die angle, extrusion ratio,
and friction coefficient on the process and the resulting material properties. The findings
indicate that a smaller die angle, higher extrusion ratio, and increased friction coefficient
all contribute to a greater required process force. While friction between the sample and die
wall disrupts uniform plastic strain distribution, increasing the die angle up to 110° and
using an extrusion ratio of 6.25 enhance strain uniformity.
