Engineering Characteristics of Drawn Filled Nitinol Tube

From Fort Wayne Metals, Inc.

The elastic behavior of various thermally set Nitinol-DFT®-Platinum1 composite wires was investigated in both axial and flexural modes. Two varieties of composite materials were analyzed, each unique in the amount of cross-sectional area made up of Platinum. The measured properties of these composites were found to be partially dependent on the mode of testing employed, the mechanical properties of the core, and the methods of processing. Theoretical relationships were used to predict the loading and unloading plateau strengths, the stress hysteresis, and the ultimate tensile strength of the composite materials. These derived values were then compared with data obtained from actual testing.
