Applications of magnesium alloys
Köhler, Tomáš ; Ročňáková, Ivana (referee) ; Němec, Karel (advisor)
This bachelor thesis includes basic knowledge of magnesium and its alloys. It also deals with their properties, division, and possibilities of heat treatment. The thesis then summarizes the application of magnesium alloys in individual branches of industries. With their usage for particular parts, a comparison with other construction materials, including the evaluation of using magnesium alloys and their advantages and disadvantages, is conducted.

Title: Physical properties of ultrafine-grained magnesium based alloys prepared by various severe plastic deformation techniques Author: Jitka Stráská Department / Institute: Department of Physics of Materials Supervisor of the doctoral thesis: Doc. RNDr. Miloš Janeček, CSc. Abstract: The objective of the doctoral thesis is the complex investigation of ultrafine-grained magnesium alloy AZ31 prepared by two different severe plastic deformation techniques, in particular the hot extrusion followed by equal-channel angular pressing (EX-ECAP) and high pressure torsion (HPT). These severe plastic deformation methods, and as well as many others, are described in detail in the introductory theoretical section. Experimental results are summarized in the following experimental part of the thesis. Mechanical properties, lattice defect structure and especially microstructure were investigated using various experimental techniques. Thermal stability of ultrafine-grained microstructure of AZ31 after EX-ECAP was investigated and the activation energies for grain growth in different temperature ranges were calculated using kinetic equation for grain growth and Arrhenius equation. Results from the dislocation density measurements proved temperature ranges of the recovery and the following grain growth. Results from the...
