Recent interest in modeling the behavior of metals at varying length scales has led to the need for accurate representations of 3-dimensional volumes in deformed and un-deformed states. Data needed for this will likely come from electron backscatter diffraction. This is hard for some metals, such as magnesium, due to difficulty polishing to a high quality surface. We have recently built an in-situ SEM serial sectioning system that utilizes a femtosecond laser to perform the machining at higher rates. With this system, large volume cuts are possible and due to the ultrashort pulses surfaces remain suitable for EBSD. This work used the in-situ SEM serial sectioning system to characterize, in 3-dimensions, the microstructure of magnesium and copper specimens deformed in tension. From the EBSD data it is possible to characterize the orientation, grain boundaries, and deformation in a tested specimen.
