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. https://ijmf.shirazu.ac.ir/article_7989_b6ba6cc828ffeac0deae414cbc9891f5.pdf
