Ultra Low Cycle Fatigue of Axisymmetric Freestanding Nanoscale Gold Films
We present ultra low-cycle fatigue experiments of axisymmetric nano-crystalline gold films of nano-thickness deformed by a spherical indenter using a recently developed freestanding membrane test. Freestanding membranes of gold were centrally deflected using a spherical indenter attached to a MEMS load cell. Fabrication of the films for these experiments yielded films 100 nm thick and 500 μm in...

15 صفحه اولSize Effects and Passivation Effects on the Plasticity of Freestanding Submicron Gold Films
The Membrane Deflection Experiment was used to examine size effects on freestanding thin film gold membranes. It is the first micro-scale testing scheme where the loading procedure is straightforward and accomplished in a highly sensitive manner while preserving the independent measurement of stress and strain. Stress-strain curves were obtained on films 0.3, 0.5 and 1.0 μm thick including memb...
متن کاملMonotonic and fatigue testing of spring-bridged freestanding microbeams application for MEMS
An electroplating spring-bridge micro-tensile specimen is fabricated to carry out a series of monotonic tensile testing on it. Freestanding thin films were loaded by performing monotonic loading/unloading and tensiontension fatigue experiments. Loading was applied using a piezoelectric actuator with 0.1 μm resolution connected through pin hole into the test chip specimen. Loads were measured by...
متن کاملPlastic deformation recovery in freestanding nanocrystalline aluminum and gold thin films.
In nanocrystalline metals, lack of intragranular dislocation sources leads to plastic deformation mechanisms that substantially differ from those in coarse-grained metals. However, irrespective of grain size, plastic deformation is considered irrecoverable. We show experimentally that plastically deformed nanocrystalline aluminum and gold films with grain sizes of 65 nanometers and 50 nanometer...
