Low energy dislocation structures caused by sliding and by particle impact

摘要: Abstract Tribological processes cause large plastic strains and strain gradients adjacent to the interface between interacting materials. For sliding wear erosion test specimens, dislocation structures observed in plastically deformed material are consistent with those expected when energy is minimized. Studies of these can contribute our knowledge deformation substructures produced at under other conditions. also create patches or layers mechanically mixed on one both contacting surfaces. This important generation typical debris. may be helpful understanding structure properties ultrafine grained two-phase
