Abstract
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 1.74 g/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°C 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 1.74 g/cm3 to 3.23 g/cm3 is successfully fabricated.
