Abstract. Plastic instability in tensile test has long been discovered and has been studied theoretically and experimentally. More recently the effect was also investigated in torsion mode and in depth sensing Vickers microhardness tests by optical- and scanning electron microscopy. We used atomic force microscopy (AFM) to investigate the effect on a series of indents. Experimental parameters were chosen so, that we should find indents with no, with a few, and with numerous slip lines. We found stripes on the inner surface of indents, but we found stripes even on those indents, where no stairs where expected. Based on considerations made on interference patterns we concluded, that the stripes are caused by multiple light stray in the AFM head, which interference pattern is significantly different from usual interference pattern on AFM images.
