The influence of cast iron inoculation with bizmut containing inoculant on structure and mechanical properties
Nyékyová, Dominika ; Navrátil, František (oponent) ; Roučka, Jaromír (vedoucí práce)
The diploma thesis deals with the modification and inoculation of cast iron with spheroidal graphite, the influence of the chemical composition on the shape and size of the graphite nodules and ferrite/perlite ratio in the structure. The aim of the practical part was to determine the effect of inoculant containing bismuth (SMW 605) on microstructure and mechanical properties of ferritic ductile cast iron GJS 400-15. The dissolving time of mold inoculant was further investigated. The samples were subjected to a tensile test, Charpy impact test, hardness test and graphite morphology and ferrite/perlite examination using standard ČSN EN ISO 945-1.
Production of steel cover
Nyékyová, Dominika ; Řiháček, Jan (oponent) ; Císařová, Michaela (vedoucí práce)
The project elaborated a literary study on deep drawing technology with a focus on reverse re-drawing operation and design of technology production of steel cover made of DC05 material. The thesis includes the technological calculations of the component required for its construction and simulation of the drawing process.
