Abstract
ECAP is a highly successful method for generating ultra-fine grained bulk material because of its equal channel angular pressure distribution. Using a custom-made die, the material is fed via a channel and into the next step. Die design features such as corner angle and channel angle have an impact on fine grain development. Commercial aluminium AA7086 was used as a sample material to assess mechanical behavior/properties before and after the ECAP procedure. This material had 90° and 20° channel angles when it was conceived and made in the lab. A die designed with an ideal parameter for use with an ECAP die, the mechanical behaviour of economically pure aluminium is investigated and analyzed in the current study. Here, the keystrokes were performed anywhere from 0 to 3 times, following the BC path. ECAP runs reduced particle size to 220 nm, and the strength increased to 368.4 MPa after three runs, the researchers found.
