A research on investment casting technology of Ti alloys

In this research, the materials and the compositions of the surface slurrie s were chosen by considering the characteristics of Ti investment casting. The effects of solid-liquid ratios on the properties of the slurry and the effects of baking temperatures on the flexural strength have also been inve stigated. Flawless shells having smooth inner surface were manufactured wit h proper technology. Ti and its alloys were melted and poured by water-cool ed Cu crucible vacuum induction furnace. The qualities of the investment ca stings made accordingly were studied and analyzed.
