Preparation and properties of porous magnesium material
 Ďubašák, Matej ; Kosár, Petr (referee) ; Březina, Matěj (advisor)
Magnesium is a lightweight metal suitable for various technical and biomedical applications due to its great strength-weight ratio and biocompatibility. The powder metallurgy (PM) of magnesium presents a modern method of porous magnesium processing, in which are reached specific mechanical properties influenced by high purity, material structure and controlled porosity during this process. This thesis deals with preparation and characterization of porous magnesium material which is prepared from a magnesium powder containing a particles with average size of 50 µm. The preparation process consists of powder pressing and sintering of green compacts. The properties of porous magnesium prepared by PM method depend on conditions of every individual process. The compaction pressure and sintering temperature were altered to optimize a preparation proces. There were examined mechanical properties (3 point bending, hardness) and optical properties (fractography and metallography). Obtained properties of porous magnesium prepared by PM were compared with technical literature.
