| Description
| - Předložené práce se soustředily na popis procesů, které probíhají v kontaktu vzájemně působících reálných těles (železniční kolo / kolejnice). Příčiny vzniku pozorovaných, tzv. bíle naleptaných vrstev, tvořených na povrchu jízdní plochy kolejnice, byly zkoumány za použití metod světelné mikroskopie, rtg.-difrakční analýzy a především pak technikou transmisní elektronové mikroskopie. Získané výsledky prokázaly, že tyto bíle naleptané vrstvy mají bcc-mřížku a typické rysy nanostruktury. Pokud stupeň deformace v dané oblasti dosáhne kritické hodnoty, dochází nejprve k rozštěpení lamel cementitu v uvažované povrchové vrstvě na hrubé částice. Posléze pak, v průběhu cyklického zatížení, jsou lamely cementitu separovány na jemnější segmenty, které nakonec dosahují morfologie velice jemnozrnných částic s velikostí několika nanometrů. Tyto mechanismy byly diskutovány v souvislosti s deformačními a teplotními jevy na kontaktním povrchu. (cs)
- The submitted research is concentrated on the description of processes occurring in the contact surroundings of mutually imposing real bodies. The nature of the white layer formed on the running surface of a railway line has been investigated using light microscopy, X-ray diffraction and mainly, transmission electron microscopy. The obtained results indicate that the white layer is of an apparently fully bcc-lattice with features of nano-structure and shows that wear surface contains carbon in solution and is thus not substantially decarburised during service. The obtained results were discussed in relation to both the deformation mechanism at the wear surface and the temperatures likely to be reached at the wheel-rail contact when the layer is formed.
