Abstract: The peculiarities of contact-induced deformation in nano-, micro- and macroscopic scale of silicon nitride ceramic composites have been studied by using quasistatic macro- and microindentation techniques, dynamic nanoindentation technique and microstructure investigations. The addition of multiwall carbon nanotubes (MWCNTs) to the ceramic matrix showed the modification of microstructure leading to the modification of mechanical behavior of material: increase of fracture toughness along with the decrease of har…
