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.
