There has been much interest recently in nanotwinned metals due to their potential for simultaneous high strength and ductility. In this study, fully nanotwinned columnar Inconel has been synthesized by magnetron sputtering with an average twin thickness on the order of nanometers and grain width on the order of hundreds of nanometers. While the as sputtered film shows tensile strengths up to 2.5 GPa, there is very limited ductility. Heat treatments up to 800° C were performed on the sputtered films in order to tune the mechanical behavior. Microstructural characterization of the heat treated films were performed at each temperature and tensile tests were performed on each film in order to determine the impact heat treatment temperature has on strength and ductility and to understand how the observed microstructures contribute to the mechanical behavior.
