Microstructural effects on the mechanical properties are deeply associated with the deformation behavior in the same scale of the microstructures. In the conventional approach is limited to post-deformation observation and speculation of the deformation mechanisms. We use a new technique of nano-scale mechanical characterization to reveal the elementally step of deformation behavior. A continuum mechanics simulation is also applied to predict the macroscopic mechanical properties from the nano-scale deformation behavior. We target metals including steels and try to understand the effects of lattice defects such as dislocations, grain boundaries, solute elements and second phase inclusions to the mechanical properties. We are going for establishing a new guide principle of materials design through the interpretation of the relationship between the microstructures and the mechanical properties.
