“…The value of activation energy E p was calculated as 334.3 kJ/mol which was higher than that of the TiZrCuPd glassy alloy without Sn addition (287.6 kJ/mol). 14) This indicates the improvement of thermal stability due to the Sn addition. The TiCu phase is considered as preferable crystallized phase for the TiCu-rich bulk glassy alloys.…”

“…14) Ti-based bulk glassy alloys are expected to be applied as biomaterials because of their excellent corrosion resistance, good biocompatibility, low Young's modulus and high recovery of strain (>2%). Some of works have been made for Ti-based bulk glassy alloys, such as TiNiCu, 5) TiNiCuCo, 6) TiCuNiSn, 7) TiZr CuNi 8) and others TiBe-based 9) systems.…”

The minor addition is fundamental to controlling the formation, manufacture and properties of metallic materials by controlling nucleation during solidification. In the present work, we investigated the effect of minor addition of Sn on glass-forming ability, thermal stability and mechanical property of TiZrCuPd bulk glassy alloy system. The substitution of Cu by 2% Sn improves the glass-forming ability significantly. The Ti 40 Zr 10 Cu 34 Pd 14 Sn 2 bulk glassy alloy rod with a diameter of 12 mm was fabricated by copper mold casting. The Ti 40 Zr 10 Cu 34 Pd 14 Sn 2 bulk glassy alloy exhibits higher energy for crystallization activation (334.3 kJ/mol). The addition of 24% Sn can enlarge the supercooled liquid region, indicating good thermal stability. TiZrCuPdSn bulk glassy alloys exhibit high compressive strength about 20002050 MPa.

“…8288) Niand Be-free Ti-based (Ti 45 Zr 10 Cu 31 Pd 10 Sn 4 ) atomized glassy powder was consolidated by the SPS process at various sintering temperatures. The samples sintered by the SPS process at a sintering temperature of 643 K with a loading pressure of 600 MPa exhibited high strength, high densification and a full glassy structure, and the potentiodynamic polarization curve showed a flat passive region after active dissolution at open-circuit potential, having a higher pitting potential.…”

Recent Progress in Ti-Based Metallic Glasses for Application as Biomaterials

2013

Ti-based bulk metallic glasses are of great interest in biomedical applications due to their high corrosion resistance, excellent mechanical properties and good biocompatibility. This article reviews recent progress in the development of Ti-based metallic glasses for the application as biomaterials. Ti-based (TiZrCuPd, TiZrCuPdSn, and TiZrCuPdNb) bulk metallic glasses without toxic and allergic elements have been developed. These glassy alloys exhibited high glass-forming ability, high strength, large plasticity, good corrosion resistance and excellent biocompatibility, which open possibilities to create Ti-based metallic glass implants. Using a spark plasma sintering process, large-size Ti-based bulk metallic glasses and the composites with hydroxyapatite, as well as porous glassy alloys having approximate Young's modulus with that of bone were developed.
