| Abstract Scope |
Nitinol has been widely studied for its shape-memory and super-elastic characteristics. Due to such special mechanical properties, Nitinol has become one of the most promising shape-memory materials for various applications in engineering fields. In this work, Nitinol structures were synthesized in a fully dense form using an additive manufacturing method using the elemental powders to arrive at the prescribed final chemical compositions. The effects of post heat treatment conditions (time and temperature) and overall chemical composition on the shape-memory characteristics of Nitinol were studied systematically to achieve a good core material suitable for various applications. The transformation temperatures of Nitinol samples were controlled accurately by less than 5°C away from the target by changing post heat treatment conditions. Synthesized structures are analyzed via various microstructure characterization techniques and their shape memory capabilities are demonstrated. |
