Fe Al single crystals of three di erent compositions (20, 28 and 40 at.%Al) in single slip orientation were studied. Evolution of their surfaces during deformation at room temperature was observed in situ in atomic force microscope. Atomic force microscopy allows us to investigate slip lines on much ner scale than traditional optical observations. Wavy slip bands in Fe Al20, cross-slip in Fe Al28 and weak slip line texture in Fe Al40 are described. Post mortem observations of surfaces of Fe Al28 deformed at elevated temperatures (in the range of yield stress anomaly) are presented as well.
