A new kind of functionally graded materials (FGM) with density gradient has come to showgreat potentials as flier-plates for creating quasi- isotropic compression waves. In order to meet the demand of lowerdensity in the front face for sueh fiier-plate, Mg with a low density of 1.74g/cm3 is selected to make a Mg-TiFGM. Mg- Ti alloys with various weight ratios were sintered by spark plasma sintering (SPS) technique at relativelow temperatures, and the processing of densification is mainly investigated. It is found that, up to 75wt% Ti, theMg- Ti alloys can be fully deasified at 560℃ due to the conglutination of Mg and the formation of a small amountof Mg- Ti solid solution. Finally, the Mg- Ti FGM with a density gradient from 1.74g/cm3 to 3.23g/cm3 is suc-cessfully fabricated.
