In a method for controlling energy damping in a shape memory alloy, provided is a shape memory alloy having a composition including at least one of: Cu in at least about 10 wt.%, Fe in at least about 5 wt.%, Au in at least about 5 wt.%, Ag in at least about 5 wt.%, Al in at least about 5 wt.%, In in at least about 5 wt.%, Mn in at least about 5 wt.%, Zn in at least about 5 wt.% and Co in at least about 5 wt.%. The shape memory alloy is configured into a structure including a structural feature having a surface roughness and having a feature extent that is greater than about 1 micron and less than about 1 millimeter. Energy damping of the structural feature is modified by exposing the structural feature to process conditions that alter the surface roughness of the structural feature. |
