Presentation Title The Effects of Inclusions on the Fatigue Performance of Superelastic Nitinol Fine Wires
Author(s) Janet L. Gbur, John J. Lewandowski
On-Site Speaker (Planned) Janet L. Gbur
Abstract Scope Advances in minimally invasive surgeries and miniaturization of medical devices place a greater demand on materials for biomedical applications. In particular, the use of fine wires/strands in various devices and tools produce enhanced performance requirements from small cross-sections of material. Successful implementation requires a better understanding of the relationships between material composition and processing to the fatigue and fracture behavior. Small wire diameters also provide challenges to material characterization, testing and evaluation. In this study, the effects of inclusions on the fatigue and fracture behavior of fine, superelastic Nitinol wires are investigated. Wire samples were examined via optical metallography and SEM techniques. Cyclic lifetime was evaluated in flex bending fatigue and rotating bending fatigue, followed by SEM analysis of fracture surfaces. The effects of material microcleanliness on the tension and fatigue performance will be summarized.
