“…Zr 56 Al 16 Co 28 metallic glass exhibits a decrease of passivation potential and an increasing of penetration rate with increasing heating temperature in Ringer's simulated body fluid at room temperature [33]. The corrosion parameters of some metallic glasses are summarized in the Table 1 [34][35][36][37][38][39]. It can be attained that the corrosion resistance of most metallic glasses after crystallized will decrease, as shown that the corrosion potential decreases and the corrosion current density increases relatively, suggesting that the passive films formed on the surface of the glassy alloy in the anodic process are protective and denser than those on the crystal alloys.…”

Metallic Glasses - Formation and Properties

Metallic glasses exhibit excellent corrosion resistance and electrocatalytic properties, and present extensive potential applications as anticorrosion, antiwearing, and catalysis materials in many industries. The effects of minor alloying element, microstructure, and service environment on the corrosion resistance, pitting corrosion, and electrocatalytic efficiency of metallic glasses are reviewed. Some scarcities in corrosion behaviors, pitting mechanism, and eletrocatalytic reactive activity for hydrogen are discussed. It is hoped that the overview is beneficial for some researcher paying attention to metallic glasses.

“…In recent years, bulk metallic glassy alloys based on titanium have been developed. [20][21][22][23][24] The progress in the design of bulk metallic glasses has also led to progress in the development of new in situ formed nano-scale structured materials, which may exhibit even better mechanical performance than bulk metallic glasses (BMGs) and/or traditional commercial Ti-based alloys. 25,26 Although it is known that BMGs exhibit high strength and large elastic strain, they usually fail catastrophically by the fast propagation of shear bands, leaving zero global plastic strain under tension.…”

The microstructure, mechanical behaviour, and biocompatibility (cell culture, morphology, and cell adhesion) of nanostructured Ti45Zr15Pd35‐xSi5Nbx with x = 0, 5 (at. %) alloys, synthesized by arc melting and subsequent Cu mould suction casting, in the form of rods with 3 mm in diameter, are investigated. Both Ti‐Zr‐Pd‐Si‐(Nb) materials show a multi‐phase (composite‐like) microstructure. The main phase is cubic β‐Ti phase (Im3m) but hexagonal α‐Ti (P63/mmc), cubic TiPd (Pm3m), cubic PdZr (Fm3m), and hexagonal (Ti, Zr)5Si3 (P63/mmc) phases are also present. Nanoindentation experiments show that the Ti45Zr15Pd30Si5Nb5 sample exhibits lower Young's modulus than Ti45Zr15Pd35Si5. Conversely, Ti45Zr15Pd35Si5 is mechanically harder. Actually, both alloys exhibit larger values of hardness when compared with commercial Ti‐40Nb, (HTi‐Zr‐Pd‐Si ≈ 14 GPa, HTi‐Zr‐Pd‐Si‐Nb ≈ 10 GPa and HTi‐40Nb ≈ 2.7 GPa). Concerning the biological behaviour, preliminary results of cell viability performed on several Ti‐Zr‐Pd‐Si‐(Nb) discs indicate that the number of live cells is superior to 94% in both cases. The studied Ti‐Zr‐Pd‐Si‐(Nb) bulk metallic system is thus interesting for biomedical applications because of the outstanding mechanical properties (relatively low Young's modulus combined with large hardness), together with the excellent biocompatibility. © 2014 Wiley Periodicals, Inc.

“…For example, annealing treatments at intermediate temperatures, i.e., between the glass transition temperature (T g ) and the crystallization temperature (T X ), can result in a certain increase of plastic strain, 32) as well as a increase of hardness. 33) However, different (and sometimes contrasting) effects are often observed after annealing depending on the exact alloy composition and the heat treatment conditions. For example, apart from causing nucleation and growth of nanocrystals, the annealing process usually affects also the amorphous matrix in different ways.…”

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

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.
