The present study systematically investigates the effect of severe plastic deformation of Nb-1wt.%Zr alloy by high pressure torsion (HPT) and multi-axial forging (MAF) on the microstructure, texture, and mechanical property evolution. Electron microscopy as well as X-ray line profile analysis (XLPA) using convolutional multiple whole profile (CMWP) fitting was employed to elucidate key differences in the as-deformed microstructures by HPT and MAF. Electron Channeling Contrast Imaging (ECCI) and Transmission Electron Microscopy (TEM) imaging techniques were utilized to substantiate the XLPA results. The samples were then annealed to study the recrystallization behavior. Mechanical properties of the as deformed and annealed samples were measured. The deformation behavior observed experimentally was then simulated by Viscoplastic Self Consistent (VPSC) model of polycrystal plasticity to reveal the differences in deformation micro-mechanisms of submicrocrystalline materials produced via a shear-based process (HPT) and a plane-strain based process (MAF).
