Fracture micromechanisms of Cu nanomaterials prepared by ECAP
Fracture micromechanisms of nanocrystalline Cu prepared by ECAP method are analysed in this paper. It follows from the analyses that the fracture micromechanism is influenced by the number of ECAP passes. Transcrystalline ductile fracture took place in the range from 1 to 14 passes, whereas mixed fr...

| Zusammenfassung: | Fracture micromechanisms of nanocrystalline Cu prepared by ECAP method are analysed in this paper. It follows from the analyses that the fracture micromechanism is influenced by the number of ECAP passes. Transcrystalline ductile fracture took place in the range from 1 to 14 passes, whereas mixed fracture (transcrystalline ductile fracture with intercrystalline facets) occurred after 15 and 16 ECAP passes. Probable reasons of different fracture mechanisms are explained. |
