| Abstract: | Ti-Sc Function-graded material (FGM) with density gradient in the thickness direction was fabricated in a vacuum furnace under conditions of hot -press sintering at 1473K and a pressure of 30MPa for two hours. The alloying mechanism of Ti-Sc FGM was that Ti, Sc and Mg additives were in solution each other under the experimental conditions. The microstructure and element line distribution images of Ti-Sc FGM were investigated by means of EPMA+EDS and TEM. The results showed that the microstructure of Ti-Sc system FGM exhibited a transition from Sc layer dispersion in Ti layer matrix to an inverse dispersion of Ti layer in Sc layer with increase of Sc content. |
| Keywords: | Ti-Sc System FGM with density gradient fabrication microstructure |
