摘要：

The present study unravels details of the micromechanical behavior of a microspecimen made of IF-steel. A triangular prism is machined via focused ion beam (FIB) and contains two ferritic grains. Four experimental tools are integrated to identify the material's crystal parameters: i) an optical confocal microscope captures height profile images, ii) an in-situ tensile stage prescribes the loading history to the macrospecimen, iii) a global Digital Image Correlation (DIC) algorithm measures the 3D surface displacement fields, and iv) an extension of Integrated-DIC for 3D displacement fields is implemented to assess the micromechanical behavior. It is demonstrated that with this methodology the identification of the boundary conditions and crystal plasticity parameters is successfully achieved. (C) 2016 Acta Materialia Inc.
