Shape memory effect in nanocrystalline NiTi alloy processed by high-pressure torsion
Shape memory effect in nanocrystalline NiTi alloy processed by high-pressure torsion
A NiTi alloy was processed by high-pressure torsion for 10 turns followed by post-deformation annealing at 673 K for various times. An anneal for 60 min gave a nanocrystalline microstructure with a superior shape memory effect and an improvement of more than 40% over the initial state.

Abstract
A NiTi alloy was processed by high-pressure torsion for 10 turns followed by post-deformation annealing at 673 K for various times. An anneal for 60 min gave a nanocrystalline microstructure with a superior shape memory effect and an improvement of more than 40% over the initial state.
