Abstract: Strain localisation in the heat resistant nanocoated steel at the stage of cracks nucleation, coalescence, and fragmentation of the nanocoating is investigated experimentally. Regularities in the self-organisation of plastic yielding processes and their relation to the deformation relief geometry are established.

Keywords: Plastic deformation, multiple cracks, crack-like defects, nanocoating, fragmentation
