Toughness of Metallic Materials and its Testing
Michalisko, Jan ; Zapletal, Josef (referee) ; Němec, Karel (advisor)
This bachelor work deals with toughness as a mechanical property of metal materials. It defines the toughness and its demonstrations. It describes the transient behaviour of some metals at the static and dynamic load. Furthermore, the work describes the particular testing methods (Charpy‘s, Izod‘s, DWT, DT, DWTT). It covers the historical consequences of toughness testing.

Using 3D Scanning for the Preparation of Steam Turbines Cast Parts for Machining
Michalisko, Jan ; Sedlák, Josef (referee) ; Madaj, Martin (advisor)
The technical paper deals with the application of 3D scanning for the preparation of cast machining which is a part of steam turbines manufactured by the Industrial Turbo machinery branch office of the Siemens Ltd. in Brno. There is a theoretic explanation of general terms which relate to the 3D digitization process in the first part. Further in the theoretic part, the used digitization systems TRITOP and ATOS are described in detail. In practical part, the analysis of the current process has been carried out and the alternate process of the cast preparation for a subsequent machining has been suggested. By means of above mentioned systems, the cast has been converted in a digital form and compared with the source CAD module. The comparison results in material allowance check and the suitable setting for a following machining process. In conclusion, the technical economic evaluation of both processes has been carried out.
