EBSD analýza mikrostruktury CP-Ti-4 pro dentální implantáty

Abstract

This bachelor thesis deals with the analysis of microstructure of commercially pure titanium (CP Ti) grade 4 (G4) processed by Equal Channel Angular Pressing (ECAP). The theoretical part deals with characteristics of titanium in general, with the emphasis on its applications in dental medicine, and subsequent comparison of CP Ti G4 with other titanium grades. In thesis there is also described ECAP method itself and its impact on the final microstructure of materials. Next part then deals with the electron backscattered diffraction method (EBSD). There are described basis of electron interactions with specimen, the principle of electron diffraction and the formation of Kikuchi lines. Afterwards there is briefly given the principle of indexing diffraction patterns and possible outputs of EBSD method. In the experimental part the specimen CP Ti G4 processed by ECAP technology in the Nanomet Ltd. was examined with light microscopy and EBSD technique as well.
