Optimalisation of casting and solidification behaviour axial turbo wheels to achieve fine-grained structure in the castings
 Matoušek, Roman ; Ňuksa, Petr (referee) ; Roučka, Jaromír (advisor)
The aim of this thesis is to investigate the influence of the structure of castings from the nickel superalloy Inconel 713 LC using rotation and cycling by casting table. The aim is to achieve a fine-grained structure and the best mechanical properties through varying the oscillation parameters during casting crystallization. Six castings of axial turbine wheel were initially casted for the purpose of this thesis. After evaluating their macrostructure, microstructure and mechanical properties, four additional axial turbine wheels were casted in order to validate the results.
