Shape memory alloys, such as Nickel-Titanium(Nitinol), are a class of metallic alloys that exhibit a unique capability for superelastic deformation (pseudoelasticity) and for reversion to a previously defined shape when deformed and then heated past a set transformation temperature (shape memory effect).
For establishing a more complete understanding of the phase transformation and another variant related with direction of molecular structure, I am doing experimental investigation into the effect of cyclic loading on the formation and propagation of stress-induced martensitic phase fronts in a polycrystalline Nickel-Titanium shape memory alloy using an in-situ optical technique called Digital Image Correlation (DIC). With this approach towards characterization, full-field, three-dimensional deformation maps are captured in real time during cycled transformations between the austenitic and martensitic phases.
