Fatigue properties of magnesium alloy AZ31 prepared by rotary swaging method

Magnesium alloys are considered to have a high potential for applications in many engineering fields. Specifically, AZ alloys are of low weight, good castability and strength and they are also fairly resistant to corrosion. Moreover, the mechanical properties can be further improved by metalworking tech- niques. Methods of severe plastic deformation are often used for this purpose. Rotary swagging, which is one of those methods, is used for tubes and rods crafting. This method allows the material structure to reach homogeneous microstructure in its full volume. There has already been a fine amount of research effort and studies done in regards to mechanical properties of AZ alloys prepared with the methods of severe plastic de- formation. The ultimate goal of this thesis is to study fatigue properties of said alloys, which have not been subjected to such research in sufficient volume as of yet.
