Controlled Initiation and Propagation of Stress-Induced Martensitic Transformation in Functionally Graded NiTi

open access: yesJournal of Alloys and Compounds, 2021
Near-equiatomic NiTi alloys are known to exhibit a thermoelastic B2–B19′ martensitic transformation, which gives rise to their unique properties of the shape memory effect and pseudoelastic effect. This transformation can be induced by the application of

A method to determine the accuracy of shape setting thin, spirally shaped Nitinol wires

open access: yesCurrent Directions in Biomedical Engineering, 2021
Electric stimulation of the auditory nerve using a cochlear implant (CI) is presumed to be superior when the electrode array (EA) is placed close to the inner wall of the cochlea. Nitinol is investigated as an actuator that enables an intracochlear shape
