Heat treatement of tool steels
Kubín, Matěj ; Moravčík, Igor (referee) ; Jan, Vít (advisor)
This thesis deals with heat treatment of tool steels. The work is divided into two parts. The theoretical part includes marking, properties and theoretical processing of tool steels. It also contains the technique which is used for sample preparation. In the experimental part there is an examination of the two common sold drills. Samples were made from the drill, on which metallographic analysis and heat treatment was performed.

Cutting performance of very fine grained end mills
Uttendorfský, Aleš ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
This diploma thesis consists of two parts. The theoretical part describes sintered carbides, their properties and manufacturing tools. Some selected problems of milling and its physical nature is discussed also. It also deals with the types and methods of tool wear testing. The aim is to compare the experimental properties of monolithic end milling cutters (short four cutting edges, uncoated carbides) of various grain sizes in two basic ways of milling - down-feed method and up-feed method. The measured values are evaluated by analysis in time series of the cutting forces and power.

Relationship between Structure and Properties of cast Ni-alloys
Smékalová, Jana ; Hutařová, Simona (referee) ; Podrábský, Tomáš (advisor)
Nickel superalloys are developed for conditions which request the corrosion resistance, the heat-resisting and the creep-resisting material. They are used for components of air turbine motors and internal combustion turbines. The efficiency of these mechanisms is elevated with increasing combustion temperature so their development is accentuated. This thesis is concerned with a relationship between a structure and properties of nickel superalloys Inconel 713LC and Inconel 738LC in this thesis.
