“…Titanium materials possess good mechanical properties, excellent corrosion resistance and high biocompatibility which make them outstanding candidates for various applications in the biomedical, aerospace and automotive industries [1][2][3][4]. Over the past years, a large number of titanium materials have been developed especially in the biomedical area [5][6][7][8][9][10]. Among them, commercially pure titanium (CP-Ti) is still one of the most commonly used metallic biomaterial for implants [1].…”

Ti and Ti-TiB composite materials were produced by selective laser melting (SLM). Ti showed an α΄ microstructure, whereas the Ti-TiB composite revealed a distribution of needle-like TiB particles across an α-Ti matrix. Hardness (H) and reduced elastic modulus (Er) were investigated by nanoindentation using loads of 2, 5 and 10 mN. The results showed higher H and Er values for the Ti-TiB than Ti due to the hardening and stiffening effects of the TiB reinforcements. On increasing the nanoindentation load, H and Er were decreased. Comparison of the nanoindentation results with those derived from conventional hardness and compression tests indicated that 5 mN is the most suitable nanoindentation load to assess the elastic modulus and hardness properties. The wear resistance of the samples was related to their corresponding H/Er and H3/Er2 ratios obtained by nanoindentation. These investigations showed that there is a high degree of consistency between the characterization using nanoindentation and the wear evaluation from conventional wear tests

“…Further modification to the chemistry of the metal is often sought however as a means of enhancing the desirable characteristics required in its intended use. For instance, Ti used in the manufacture of screws for attaching bone to bone or soft tissue to bone can be mixed with other metals for example copper, nickel, cobalt or chronium to form an alloy with increased shear strength and the ability to withstand higher biomechanical loads [23]. Similarly, coating the surface layer has been shown to enhance the osteoconductive properties of the metal (e.g.…”

“…Some examples include anomalously low elastic modulus in Fe-Mg microcomposites [10], outstanding strength in metal-polymer nanocomposites [5,[11][12][13] fabricated from nanoporous metals [14][15][16][17][18][19], and significantly enhanced plastic deformability in metallic glass composites [20,21]. The design of non-equilibrium composite microstructures in as-cast nanostructured titanium alloys [22][23][24][25][26] leads to the high strength and good plastic deformability required for structural and biomedical applications [27,28]. One of the promising processing methods for the design of advanced materials with non-equilibrium composite microstructures is the annealing of metallic glasses [21,29].…”

Fabrication of Metastable Crystalline Nanocomposites by Flash Annealing of Cu47.5Zr47.5Al5 Metallic Glass Using Joule Heating

Flash Joule-heating was applied to the Cu47.5Zr47.5Al5 metallic glass for designing fully crystalline metastable nanocomposites consisting of the metastable B2 CuZr and low-temperature equilibrium Cu10Zr7 phases. The onset of crystallization was in situ controlled by monitoring resistivity changes in the samples. The effect of heating rate and annealing time on the volume fraction of the crystalline phases and mechanical properties of the nanocomposites was studied in detail. Particularly, an increase of the heating rate and a decrease of the annealing time lead to a lower number of equilibrium Cu10Zr7 precipitates and an increase of tensile ductility. Tailoring of these non-equilibrium microstructures and mechanical properties may not be possible unless one starts with a fully glassy material that opens new perspectives for designing metastable nanomaterials with unique physical properties.
