Indentation Technique for Determination of Mechanical Behavior of Nanomaterials (Bulk and Coatings)

摘要

The use of the indentation teclinique (local loading method LLM) for the characterization of mechanical properties of nanostructured materials is presented. Vickers hardness, HV; Meier hardness, HM; plasticity characteristic, δ_H; superplasticity parameter, m; at various temperatures were determined; stress-strain curves were obtained using samples of the bulk materials: nanostructured Ni and Zn-22wt.% Al alloy, and thin surface layer in a rail being used.
