Abstract

The mechanical properties of nanowires consisting of nanoporous gold are studied experimentally. The nanoporous gold is synthesized from dealloyed "white gold" leaf (Au_37.4 and Ag_62.6 in at.%) into a free-standing dog-bone-shaped specimen with a gauge section 7 μm long, 300 nm wide, and 100 nm thick. The elastic modulus, residual stress, and yield stress are measured by deflective tensile testing and nanoindentation, and are about 9 GPa, 65 MPa, and 110 MPa, respectively.
