N2 - Metal matrix composite comprising a multiphase magnesium matrix and titanium particles fabricated by hot pressing was characterized. Powder mixture of the Mg:Ti:Al at weight ratio equal to 10.5:6.1:3.4 was sintered at 640, 650 and 660°C whereas other parameters were held constant. Thermal effects during heating and cooling of powder mixture were measured by differential scanning calorimetry (DSC). Microstructure of composite was characterized by scanning electron microscopy (SEM) with a use of X-ray energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD). For all conditions of components consolidation α-Mg, α-Ti, Mg17Al12 and Al3Ti were identified. It was revealed that dispersion and location of Mg17Al12 and Al3Ti compounds depended on sintering temperature. Measurements of hardness and density of obtained non-porous composite gave approximate results of 130 HV and 2.7 g/cm3 respectively.
