Abstract: Molybdenum alloys and titanium alloys were sintered at 1473K for 1h under a pressure of 30MPa. It was found that the addition of Al can increase evidently the relative density of sintered Mo-Fe alloys. The Fe-Al additives are also suitable for the sintering of titanium alloys, and the Mo alloy and Ti alloy can be densified concurrently with the same additives 3%Fe-1.5%Al. The experimental results also showed that during the sintering of Mo-Ti alloys the Fe-Al sintering aids promoted the formation of Mo-Ti solid solution, but the solid solution reaction occurred at the low sintering temperature of 1473K is inadequate. Finally, Mo-Ti system functionally graded material has been successfully fabricated. Its density changed gradually from 9.52 g/cm3 to 4.48 g/cm3 in thickness direction. Such a material can be used in dynamic high-pressure technology.
