Abstract
The presence of carbide and oxide inclusions in nitinol, and their influence on the fatigue performance, has been an important consideration in the medical device community. Microcleanliness, as determined by inclusion size and inclusion density, has often been cited as a potential factor influencing the fatigue behavior of the material. However, no comprehensive study has been conducted to determine their impacts on the fatigue behavior. The objective of this effort was to understand the influence of the inclusions present in the material on the fatigue behavior.
