Abstract

The purpose of this paper is to review the current processing and resultant properties of Nitinol for medical device applications. The melting and fabrication of Nitinol present a number of unique challenges because of the strong sensitivity of the alloy system to chemistry and processing. The first part of this paper will summarize the effect of alloy fabrication on key material properties, vacuum-melting techniques, hot working, and cold working. The effects of the final shape-setting heat treatments on transformation temperature and mechanical properties for medical devices will also be reviewed.
