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 • using two different processing routes. Compression testing was us
## Abstract The microstructure of the CuNi alloy specimen ER is mainly elongated coarse grains. However, the microstructure of the specimen EH is inhomogeneous and some recrystallized sub‐grains form. In addition, the misorientation angles of the specimens ER and EH are mainly smaller than 15°, sh
