X-ray elastic response of metallic thin film supported by polyimide substrates

Abstract

This paper illustrates the insights gained on the mechanical response of metal-coated soft polymer substrates using in-situ tensile testing under synchrotron x-rays. Progress made in external loading (uniaxial and biaxial) and detection capacities is reviewed since they allow scrutinizing multiphased specimens in a reasonable time frame. In general, the microstructure (grain morphology, preferential crystallographic orientation) has to be incorporated into the models used to interpret the experimental data.
