Nano-indentation at temperatures up to 600 °C has been applied the (0001) surface of highly oriented pyrolytic graphite using a spherical diamond tip (?10 ?m diameter). Cross-sectional observations indentations by dark field scanning transmission electron microscopy show an increased tendency high temperature for inelastic deformation buckling crystals with kink formation.

Plastic deformation of DC04 steel is regarded as a nonlinear, complex, irreversible, and self-organized process. The stress–strain time series analysis provided the possibility to identify areas (quasi-)elastic deformation, plastic necking. latter two regions are most informative. area inelastic reflected by collective, processes that lead formation pores, finally, development microcracks gener...
