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