Preparation of Mg-Al-Ti bulk materials via powder metallurgy

Popis výsledku v původním jazyce

Bulk materials based on the Mg–Al–Ti system were prepared using traditional methods of powder metallurgy, as well as using the sprak plasma sintering (SPS) method. The microstructure of the material, elemental and phase composition was examined. Subsequently, Vickers hardness and flexural strength were measured, and fractographic observation of the fracture surface was performed. It was found that the aluminum was completely dissolved during sintering and subsequent heat treatment, but the titanium particles remained almost intact in the material and worked as a particulate reinforcement. X–ray diffraction spectroscopy detected multiple phases, such as magnesium phase β, magnesium–aluminum solid solution, pure titanium, and titanium nitride. Titanium nitride could be formed because of the reaction of titanium and the nitrogen atmosphere used during sintering. Materials prepared by methods of conventional powder metallurgy showed increased porosity compared to materials prepared by the SPS, resulting i
