Ti-based alloy Ti64Zr5Fe6Si17Mo6Nb2 （At %） and Ti70Zr6Fe7Si17 （At %） ribbons with a width of 3-5 mm and thickness of about 80 um were fabricated by a single roller spun-melt technique. The feature of the alloy composition satisfies the three empirical rules. Amorphous structures of both alloys were confirmed by the X-ray diffraction pattern. To test the biocompatibility, both alloys were cultivated in the simulate body fluid （SBF）. After 15 days, the Ca phosphates depositions on alloys surfaces were gained. Moreover, n（Ca）/n（P） atom ratio of the deposition is about 1.6/1, which approaches to that of human bone—1.66/1, suggesting that both alloys were with a favorable biocompatibility.
