The scanning electron microscope (SEM) image shows the plastic flow response of square (4 µm × 4 µm) single crystal Fe-3%Si steel (BCC) micro-pillars oriented for single slip during in-situ SEM compression experiments. When the pillar edges are fabricated (using focused ion beam micromachining) parallel to the slip plane traces on the surface, easy glide along progressive single slip planes gives the distinctive bent shape to the pillars.
