Abstract Scope |
Thin metallic films are common components used in fabrication of micromechanical systems with expanding use in various areas of applications including consumer electronics, automotive, medical or communication applications. The materials used in these components are frequently subjected to a range of operating velocities, frequencies and accordingly high strain rates during vibrations. Therefore it is necessary that the mechanical properties of these materials meet strict requirements and they need to be thoroughly tested. Small scale localized material properties can be revealed by in-situ deformation testing in transmission electron microscopes using a holder with a fully integrated picoindenter. This method allows direct observation of nano-scaled samples during mechanical measurements and simultaneous acquisition of load-displacement curves. Molecular dynamics simulations were used to predict the behavior of aluminum-based thin films during deformation experiments and results were compared with corresponding experimental results. |
