Abstract

In order to develop a new kind of medical implant material, the microstructure and mechanical properties of cast Ti-Si alloys were investigated usingsmalt-size ingots prepared by a dental casting machine. The results show that the addition of silicon significantly changes the microstructure of titanium alloys. The Ti5Si3 intermetallic compound precipitation occurs in diematrix of alpha and beta phases, when the silicon content is over 1.33 mass%. The compound is observed as a netted structure around grain boundaries of me titanium matrix when die silicon content exceeds 2.35 mass%. In addition, the Ti-Si alloys show a good combination of strength and ductility in a wide range of silicon content hi contrast to the purl titanium and Ti-6Al-4V alloys. The cast Ti-Si alloys re promising candidates for dental applications because of a good balance between strength and ductility.
