Notes:
2 was examined by AFM in contact mode. On loading the polycrystalline sample the surface roughness increases and visible mesoscopic structures of about 25 μm in diameter appear. The fractal dimension df of the surface topography was analyzed and it was found that df starts to increase at the yield strength and finally ends in a plateau. Investigation of the nickel monocrystal showed the formation of well-characterized slip bands and non-regular substructures beyond a short elastic region. The development of the fractal dimension is similar to that of the polycrystalline steel sample. The results obtained are discussed in the framework of mesomechanics.
