The hierarchical texture evolution of RE-component during friction stir processing of Mg-RE/SiCp composite

[Display omitted] •Splitting of basal and prismatic poles in a friction stir processed Mg-RE composite.•Simultaneous activation of non-basal slip systems during friction stir processing.•Sequential evolution of RE-texture component during friction stir processing.•Formability improvement owing to the remarkable anisotropy decrement. This study offers a new approach to investigate the RE-texture evolution in a friction stir processed (FSP) Mg-RE/SiCp composite. Detailed textural analyses suggest that the new orientation of //PD, has been evolved through a sequential crystallographic rotation owing to the simultaneous activation of prismatic and pyramidal slips. The effect of this textural evolution on the stretch formability of FS-processed materials is also examined via normal and planar anisotropy analyses.
