Pipe welding of stainless steel and titanium
Dušek, Vojtěch ; Sigmund, Marian (referee) ; Kubíček, Jaroslav (advisor)
This master's thesis deals with the selection and evaluation of the appropriate welding technology for stainless steel and titanium alloys. Describes advantages and disadvantages of selected technologies. The experiment compares the mechanical properties, the heat input and the resulting surface structure of the welded samples. In conclusion, the thesis deals with the technical - economic evaluation of selected welding technologies.

Productive Machining of Titanium Alloys
Čejka, Libor ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
The aim of the thesis is to analyze the production costs and optimize cutting conditions for high-feed face milling of titanium alloy Ti6Al4V. In the experiment were changed cutting conditions, such as cutting speed vc and feed speed vf. During the experiment were checked cutting forces by dynamometr. Furthermore, surface roughness and tool wear is observed.

Productive Machining of Titanium Alloys - I.
Lengálová, Barbora ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
This study consists of theoretical and practical part. Theoretical part of study resumes properties of titanium and it alloys and mentions application field and the way of production. Study includes review of machining strategies of titanium alloys. The materials for cutting tools and various types of tool wear are included. The experimental part of study consists of two partial experiments focused on the face milling by the ball – end milling cutter. First part is focused on facial milling of the inside part of spherical surface by the ball – end milling cutter and thus its surface roughness rating. The second part of experiment focuses on the milling of flat surface by the ball – end milling cutter and consequential analysis of cutting forces when the chip thickness is variable.

Titanium, Alloys and Intermetallics for Biological and Industrial Applications
Vespalec, Vítězslav ; Jech, David (referee) ; Čelko, Ladislav (advisor)
The creation of this Bachelor´s thesis was performed as a search retrieval, which includes basic information about titanium and its alloys. In the first chapter is stated history of titanium manufacturing. Following chapter include the most important property of pure titanium, such as alotropic modifications of the crystal grid, chemical, physical and technological characteristics, there is also space, that is assigned for using contemporary division of titanium alloys, detrimental effect of impurity, shape memory effect and intermetallics instance. Third part concern about selected application in industry. The conclusion pursue about biocompatibility factor and possibility use titanium and its alloys in implantology and dental applications.

Mechanical properties of titanium alloys
Prudíková, Alena ; Liškutín, Petr (referee) ; Věchet, Stanislav (advisor)
This bachelor thesis was created in a form of literary search and it summarizes the basic information of Titanium and its alloys. The most significant features, such as its position in Periodic Table of the Elements, allotropic modifications and their crystal lattices, chemical or physical qualities, are mentioned in the first chapters. The attention was also paid to both the mechanical and the technological qualities of titanium as such, including the effect of impurities that may be very significant. General and summarized information about the history of titanium, as well as current directions in the development of its alloys are discussed in chapter 1.3. As a following, the information about production and the methods used during the production are discussed in chapter 2. Distinct part of the thesis depicts the partition of concrete titanium alloys and the heat treatment of them. The TiAl6V4 alloy was described in details, since it is the most widely used, therefore the most often produced titanium alloy.
