“…The structure of the Ti-15Mo alloy, quenched from 810 С, consisted of large equiaxed recrystallized b-grains with an average size of 33 AE 2 mm [16] and not more than 5% athermal v-phase, with a particle size of below 5 nm. Figure 1 displays the TEM images of the HPT-processed structure, taken from the middle of the sample's radius.…”

In this paper, the processes of grain refinement and phase transformations in the Ti-15Mo b-alloy during high-pressure torsion (HPT) at room temperature are investigated. The non-monotonic character of the variation of the v-phase volume fraction has been demonstrated for an increasing number of turns; in particular, the HPT processing of 1 turn leads to the precipitation of 10% v-phase from the b-matrix, but at 10 turns of HPT a reverse phase transformation is observed. It is shown that nanostructure formation with a minimum content of the v-phase allows for achievement of significant strengthening in the alloy while preserving a relatively low elastic modulus.

“…It is worth focusing the future research of n-Ti on achieving even higher ultimate strength and yield strength in dependence on reduction of the modulus of elasticity, which could approach the modulus of elasticity of jaw-bone. [27] Recent studies show [31] that nanostructured b-Ti alloys processed by SPD quite satisfy these requirements and the use of such alloys in dental implants with improved design and functionality is rather promising.…”

“…[1,29] Complications were caused by the processes of tissue inflammation around the implant, which can result in the progressive destruction of the bone tissue surrounding the implant. [31] Due to different reaction of living tissues, such cases do still happen in modern dentistry and may be reduced by creating bioactive coatings on the surface of implants that enhance the recovery of bone tissue around the implants and increase their biocompatibility. Our work on this issue is still in progress with the aim to create the bioinert and bioactive coatings for titanium implants.…”

The paper presents the results of developments of nanostructured Ti with enhanced strength in the form of long-length rods. Using the technique of ECAP-Conform and drawing, rods with record strength properties were obtained, with UTS 1 330 MPa and endurance limit based on 10 7 cycles of 620 MPa. The developed processing route is quite effective and can be implemented at the commercial scale. It is shown that the use of nano-Ti rods allows for creation of dental implants with improved design and a smaller diameter. Such modern miniature implants with the diameter of 2.4 and 2 mm were manufactured by the "Timplant" company and the results of successful clinical trials are presented.
