Structure and Properties of Titanium and Titanium Alloys

Chemical and topographic analysis of treated surfaces of five different commercial dental titanium implants

“…The XRD measurements identified crystal structures of Ti and titanium hydride (TiH 2 ) in group 1, Ti and anatase (TiO 2 ) in group 2, Ti in group 3, Ti and HA in group 4, and Ti in group 5. Ti and HA have hexagonal close-packed crystal structure with lattice parameters of a = 0.295 nm, c = 0.468 nm, and a = 0.94344 nm, c = 0.68815 nm, respectively 12,13 , anatase has a tetragonal structure with lattice parameters of a = 0.3785 nm, c = 0.9514 nm, 14 and TiH 2 has a face-centered cubic crystal structure with lattice parameter of a = 0.4448 nm 15 .…”

An Experimental and Theoretical Multi-Mbar Study of Ti-6Al-4V

“…The commercial and industrial importance of the two-phase ternary alloy Ti-6Al-4V (wt %) is well documented and known to be heavily dependent on its mechanical properties (see for example [1]). Ti-6Al-4V (hereafter referred to as Ti64) crystallizes predominantly in the twoatom  -phase (hexagonal-close-packed or hcp) at ambient conditions, with a much smaller fraction by volume crystallizing in the  -phase (body-centred-cubic or bcc) around the grain boundaries.…”

Strain-Dependent Damping of Ti-10V-2Fe-3Al at Room Temperature

“…• C [10]), since it separates the single β-phase field from the two-phase (α + β)-field [4]. The specimens were heated up to 800…”

“…Moreover, titanium alloys offer a manufacturing versatility due to their availability in different structural states presenting different allotropic microstructural changes, such as α-and β-titanium alloys [4]. Therefore, recent research studies on titanium alloys are concerned with the investigations of different thermo-mechanical processing methods and their influence on the mechanical behaviour of titanium alloys, involving elastic/plastic deformations, fatigue, creep, fracture [5], and damping [6].…”
