A new fundamental route entitled 'Route-R' is introduced to refine the grains in the material through Equal Channel Angular Pressing (ECAP) process. In route R, specimen is inverted to the original position in each ECAP pass. In the present work, AZ61 alloy is processed using ECAP process for three different fundamental routes mainly route A, route Bc, and route R. ECAP experiment is carried out on AZ61 alloy at lower temperature of 483 K up to two passes. Microstructural characterization isdoi:10.1016/j.jma.2014.04.002 fatcat:c4mhxecbi5ghlnsmizek5jxtpi
