The doctoral study programme in Manufacturing Technology is focused on production sciences and technologies, namely machining, forming, welding, foundry technology, surface treatment technology, including automation of production preparation and automation of production processes that use and require these technologies.
During the study, students will gain knowledge of applied mathematics, physical metallurgy, experimental theory and optimization of technological processes, along with other theoretical and practical knowledge closely related to the selected area of doctoral study.
The aim of the doctoral study programme is to prepare highly qualified staff for scientific work in the field of engineering technology. The study is focused on the knowledge of the theoretical basis of the whole field and also on a detailed acquaintance with the most important findings in a narrower focus, which are followed by the topics of the dissertation. The study is focused on preparation for scientific work in the chosen field and the achieved level of knowledge is presented at the state doctoral examination.
The ability to achieve original scientific results is demonstrated by the elaboration and defence of the dissertation. After a successful defence of the dissertation, the graduates of the doctoral study programme are awarded the academic title "Doctor" (abbreviated to Ph.D. after the name).

In the doctoral study of the Manufacturing Technology programme, it is possible to specialize in the field of machining technology and its optimization, forming and welding technology, foundry technology, production management, machine modelling applications and computer simulations. Doctoral students are able to participate in all forms of research, contract development and economic cooperation with industrial companies, where they solve advanced problems of technical practice. They also have the opportunity to take advantage of short-term and long-term internships and study stays in our country and within the EU in cooperation with foreign universities.
Graduates of the doctoral study program Engineering Technology have comprehensive professional skills and knowledge of production technologies, methods of their management and planning, have knowledge in the field of materials science and engineering in application to selected production technologies, both theoretical and practical.
Graduates of the doctoral study programme in Manufacturing Technology are expected to be employed in leading positions associated with the technical and technological preparation of production, its management and further development.
Graduates will also be employed as research and development staff in applied research centres as well as academic staff at universities and academic institutions.

Graduates of doctoral studies are equipped with very good theoretical and professional knowledge and therefore have a wide range of employment opportunities in professional or management positions within state and private engineering or interdisciplinary manufacturing companies, from small and medium-sized companies to large joint stock companies. The acquired knowledge can also be used as research and development workers or private entrepreneurs in our country and abroad.

See applicable regulations, DEAN’S GUIDELINE Rules for the organization of studies at FME (supplement to BUT Study and Examination Rules)

The rules and conditions of study programmes are determined by:
BUT STUDY AND EXAMINATION RULES
BUT STUDY PROGRAMME STANDARDS,
STUDY AND EXAMINATION RULES of Brno University of Technology (USING "ECTS"),
DEAN’S GUIDELINE Rules for the organization of studies at FME (supplement to BUT Study and Examination Rules)
DEAN´S GUIDELINE Rules of Procedure of Doctoral Board of FME Study Programmes
Students in doctoral programmes do not follow the credit system. The grades “Passed” and “Failed” are used to grade examinations, doctoral state examination is graded “Passed” or “Failed”.

Brno University of Technology acknowledges the need for equal access to higher education. There is no direct or indirect discrimination during the admission procedure or the study period. Students with specific educational needs (learning disabilities, physical and sensory handicap, chronic somatic diseases, autism spectrum disorders, impaired communication abilities, mental illness) can find help and counselling at Lifelong Learning Institute of Brno University of Technology. This issue is dealt with in detail in Rector's Guideline No. 11/2017 "Applicants and Students with Specific Needs at BUT". Furthermore, in Rector's Guideline No 71/2017 "Accommodation and Social Scholarship“ students can find information on a system of social scholarships.

The Doctoral Study Programme in Manufacturing Technology is a continuation of the currently accredited master's degree programme in Manufacturing Technology (N-STG), with specializations in Engineering Technology (STG), Engineering Technology and Industrial Management (STG), Modern Lighting Systems (MTS) and Foundry Technology (N-SLE) without specialization.
In the study of Manufacturing Technology, it is possible to specialize in machining technology and its optimization, forming and welding technology, foundry, production control, machine modelling applications, computer aided manufacturing technologies, computer simulations and thus allows to continue in the third stage of study. On the basis of a successful defence and achieving the scientific degree of Ph.D. the graduate demonstrates the ability of scientific work.

1. Advanced methods of laser and hybrid welding of high-alloy materials.

   The main goal of the dissertation is the use of advanced methods of laser and hybrid welding of high-alloy materials for the creation of anti-corrosion or abrasive-resistant refining layers, a comprehensive study of the properties of the resulting layers with regard to process parameters, the type of base material, and finally the optimization of the welding process in terms of maximizing the achievable properties. It is assumed that the technology of laser welding of powder material (DLD), then laser welding of wire (DLWD) and finally hybrid Laser-MIG welding is used. A partial goal of the work will be a mutual comparison of the properties of the welded layers created by the used technologies in terms of mechanical properties, microstructure, abrasion resistance, corrosion properties and other parameters. As part of the solution, the use of numerical simulations is assumed with the aim of predicting the properties of the resulting layers.

2. Joining of hardenable Al alloys for maximum mechanical properties

   In view of the weight reduction of ground vehicles, hardenable Al alloys are also being massively used for components subjected to high static, dynamic and fatigue loads. In the integral strength of the stressed assembly, welded joints are considered as a weak point, because the weld causes a reduction in the strength of these alloys, thus limiting their use. The aim of this work is to compare and find a suitable technology for joining parts made of Al hardenable alloys with respect to the highest possible mechanical properties, including fatigue. Al hardenable alloy sheets will be welded by MIG/TIG, laser and friction stir welding (FSW), or alternatively by bonding, and all necessary quality and mechanical tests will be performed. Process and technological optimisation is envisaged to achieve maximum mechanical properties. The result of the work is to be a comprehensive evaluation of the joining methods with respect to strength, but also the complexity of the process.

1. Control of oxygen content during metallurgical processing of copper alloys

   The main objectives of the dissertation are in the field of measurement and control of oxygen concentration during metallurgical processing of copper alloys. Oxygen and its concentration in the melt has a significant influence not only on the course of metallurgical reactions but also on the mechanical, technological and functional properties of copper alloys. The control of the oxygen content also strongly influences the dissolution of hydrogen in these alloys and the tendency to form endogenous bubbles. The control of the oxygen content in copper alloys is achieved by controlling the metallurgical reactions in combination with the precipitation deoxidation of the melt. The type of deoxidising element used and its concentration also affect the electrical conductivity of these alloys, which is essential in the production of castings for electrical conductive purposes. A sub-objective of the work will be to verify the deoxidation of copper alloys using elements with high deoxidation capacity such as magnesium or lithium and to verify their effects on the mechanical and functional properties of these alloys.
