We employed high-temperature nanoindentation to examine the mechanical behavior of nanotwinned silver. A set of silver samples were made using magnetron sputtering. The samples showed strong <111> texture that increased with increasing deposition rate. The samples also showed parallel twin boundaries with spacings of about 8-10 nm, independent of the texture. To better understand possible deformation mechanisms leading to high strength and thermal stability, in-situ and ex-situ high temperature nanoindentation experiments were employed. The strain rate was determined as a function of temperature, from which activation energies for the deformation were determined. This presentation will focus on a discussion of parameters affecting the mechanical deformation of NT silver films, such as activation energy, grain size, twin boundary spacing, and <111> texture parameter.
