Analysis of different ways/speed of cooling Al casings during their solidification and influence to the mechanical properties, structure and dendrite arm spacing of the final castings
 Holčapek, Jiří ; Vašťák, Patrik (referee) ; Horáček, Milan (advisor)
This master´s thesis deals with finding the best way to cool a ceramic shell mould during solidification of the melt to achieve the requiered values of mechanical propeties. During the experimental part we tried different cooling methods. This involved blowing the shell with compressed air, submerge in water and wetting in a quenching polymer solutions at different speeds. The best way reaching the highest values of machanical properties was chosen the method of rapid submerge of the shell mould in a solution of quenching polymer of a specific concentration. The mechanical properties have been achieved.
