Two-way shape memory in a nanoscale sample of Ti49.5Ni25.5Cu25.0 alloy with a partially ordered structure
The dependence of the thermomechanical properties and structure of rapidly quenched Ti49.5Ni25.5Cu25.0 alloy on the annealing conditions has been studied. A sample with a partially ordered structure is found to have two-way shape memory effect during single deformation. An alloy sample 17 × 10 × 0.07 μm in size has been prepared and trained. It is shown to demonstrate two-way shape memory behavior.
