| Abstract: | Ti-Sc alloys of different designed ratio were hot-press sintered at 1 473 K under the pressure of 30 MPa for two hours in a vacuum furnace. Ti-Sc FGM whose density changes quasi-continuously from 3.0 g/cm~(3) to 4.5 g/cm~(3) in the thickness direction was obtained under the same experimental conditions. Mg additive can greatly increase the densities of Ti-Sc alloys. The microstructures of Ti-Sc FGM and Ti-Sc alloys were investigated by means of EPMA EDS. |
