The curriculum concentrates on the comprehensive study of materials properties and failure processes from the point of view of physics and physical metallurgy. Students should develop capability to apply their knowledge in inventive manner to new technologies and materials, such as plasma spraying, special methods of thermo-mechanical and thermo-chemical treatment, etc. Special attention is paid to the degradation processes and to the synergetic effects of various materials properties on material failure. The subjects of study are metallic and non-metallic materials, e.g., structural ceramics, polymers, amorphous and nanocrystalline materials and intermetallics.
The Ph.D. programme requires proficiency in mathematics and physics at the MSc. degree level obtained from Faculty of Science or Faculty of Mechanical Engineering.

1. Welding of difficult to weld mateials using concentrated sources of energy

   The use of an electron beam or laser beam for welding refractory materials or metallurgically unsuitable combinations of materials is often used in special areas of industry such as energy, nuclear industry, or other special applications. The use of concentrated energy sources makes it possible to achieve a very small width of the melt pool while maintaining large thicknesses of the welded material. This makes it possible to reduce the area with the occurrence of mechanically unsatisfactory phases, but it is very difficult to completely prevent the formation of brittle phases in metallurgically complicated welds. The work will focus on the study of the formation of specific phases and microstructures in welding difficult to weld materials and then the aim will be to design a general methodology for solving metallurgically complicated welds in order to achieve optimal microstructure without the occurrence of strength limiting structures or phases.
