Abstract
The microstructure and mechanical properties of Ti alloy contained 40 mass % Nb at megaplastic deformation effect is described. It was proved that the deformation effect including the multiple abc-pressing and multi-pass rolling and further pre-recrystallizing annealing enhances the formation of ultra-fine grained structures with mean element size of 0.3 μm or less, involving stable (β + α)-phase composition and metastable nanosized ω-phase in the alloy. This, in its turn, significantly improves the mechanical properties and simultaneously preserves low elastic modulus level.
