Welding strength of NiTi wires [PDF]

Dental Press Journal of Orthodontics, 2018
ABSTRACT Objective: To identify the appropriate power level for electric welding of three commercial brands of nickel-titanium (NiTi) wires. Methods: Ninety pairs of 0.018-in and 0.017 × 0.025-in NiTi wires were divided into three groups according to their manufacturers - GI (Orthometric, Marília, Brazil), GII (3M OralCare, St.

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

Current 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

Phase transformation and deformation behavior of NiTi-Nb eutectic joined NiTi wires [PDF]

Scientific Reports, 2016
AbstractNiTi wires were brazed together via eutectic reaction between NiTi and Nb powder deposited at the wire contact region. Phase transformation and deformation behavior of the NiTi-Nb eutectic microstructure were investigated using transmission electron microscopy (TEM) and cyclic loading-unloading tests.
