## Abstract The microstructure of the Cuο£ΏNi alloy specimen ER is mainly elongated coarse grains. However, the microstructure of the specimen EH is inhomogeneous and some recrystallized subβgrains form. In addition, the misorientation angles of the specimens ER and EH are mainly smaller than 15Β°, sh
In this study the flow properties after equal channel angular pressing (ECAP) were investigated using commercial purity aluminum. Commercial purity aluminum samples were subjected to ECAP for up to four passes with a die angle of 90 β’ using two different processing routes. Compression testing was us

Experiments were conducted on two commercial aluminum alloys, Al-6061 and Al-7034, to evaluate the development of any plastic anisotropy during processing by equal-channel angular pressing (ECAP). After pressing through various numbers of passes, compression tests were conducted at room temperature
