Microstructure and mechanical properties of Ti40Nb alloy after severe plastic deformation

Abstract

The study presents the analysis of microstructure, phase composition and mechanical properties of Ti40Nb alloy exposed to severe plastic deformation. It was shown that isothermal multi-axial forging and further multi-pass rolling intensify the formation of ultra-fine grained structure in the bulk of a billet with the average element size of 0.3 μm. Such ultra-fine grained structure considerably improves the alloy mechanical properties.
