Abstract Scope Lightweight Magnesium (Mg) alloys have the suitable potential to be utilized as structural components for automobile and aerospace application. However, the major drawback is its poor strength and formability. Equal channel angular pressing (ECAP) is a widely known severe plastic deformation technique to obtain ultrafine grains to improve these properties. In this work, Mg was deformed by ECAP via route A, BC, and C up to the 8th pass. The role of the changes in strain path during ECAP via these different routes on the microstructure and texture evolution was investigated. The visco-plastic self-consistent model was used to simulate the texture and understand the deformation mechanism for the different ECAP routes. The effect of strain path change on the strain hardening behaviour and mechanical properties were comprehended.
