Strucure and mechnical properties of cold sprayed Ti-6Al-4V layer
Sabela, Jakub ; Zelený, Martin (oponent) ; Řehořek, Lukáš (vedoucí práce)
Diploma thesis deals in the first part with recent knowledge of cold spray, its mechanism and parameters of deposition, advanced coatings made by cold spray and their applications, knowledge of Ti-6Al-4V coatings and their heat treatment. Deposit of Ti- 6Al-4V powder was made by cold spray process. In experimental part, microstructure and mechanical properties of supplied and its heat treated material were observed and examined. Mechanical properties and microstructure remained unchanged by annealing at 600 °C as in the case of supplied material. Recrystallization occured in microstructure of and phases by annealing at 800 °C. Grains were emerged in microstructure and mechanical properties were decreased. Mechanical properties were improved by annealing at 900 °C due to quenching. Microstructure consists of and ’ phases. Mechanical properties were the worst for annealed material at 1000 °C because of coarsed grains. Material which was annealed at 800 °C, quenched and precipitation hardened had the best microstructure and mechanical properties.

Slitiny s tvarovou pamětí
Sabela, Jakub ; Doležal, Pavel (oponent) ; Němec, Karel (vedoucí práce)
Cieľom bakalárskej práce je spracovať prehľad materiálov s tvarovou pamäťou na báze kovu. V prvej časti bakalárskej práce som sa vyjadril k histórii a problematike princípu materiálov s tvarovou pamäťou. V druhej časti som tieto materiály rozdelil podľa štruktúrneho hľadiska a zaoberal sa najpoužívanejším pamäťovým materiálom v praxi. Uviedol som jeho výhody a nevýhody. Ďalšia časť bola venovaná výrobe, tepelnému a mechanickému spracovaniu. Následne som uviedol najpoužívanejšie aplikácie v praxi. Na záver som sa vyjadril k budúcnosti materiálov s tvarovou pamäťou.
