“…Figure 4(c) are shown a produces with platy shape morphology dominated by the Mo element. As the 3% to 9% Cu element are added, the stress value decreases, but the use of molybdenum (Mo) and copper (Cu) is intended as a good β-stabilizer in titanium alloys [8,11].…”

“…The development of TiNi alloys with the addition of a percentage of Cu elements in the range of 1% to 10%, the result is a decrease in stress values compared to TiNi alloys without the addition of Cu. However, based on operating at increase temperature, when deformation occurs, the stress value is below 28 MPa [11]. Ti-6Al-7Nb was fabricated via mechanical milling at the temperature of sintering with variation of 1150℃ tested against mechanical properties with the hardness test analyzed with X-ray diffraction to produce the lowest coefficient of friction and wear rate.…”

Titanium alloys are currently widely explored and produced for applications in various engineering fields. Alloying metal elements such as Mo, Cu, and Mn bring more advantages among them to help improve the mechanical properties of titanium alloys. This study is intended for the evaluation of mechanical properties through compression and hardness testing performed on a Ti-10Mo alloy with copper addition by powder metallurgy. Ti-10Mo alloys with the addition of copper contents of 3 wt% Cu, 6 wt% Cu, and 9 wt% Cu were prepared to optimize the properties of Ti-10Mo-xCu alloys. With the addition of 3 wt% copper, the compressive strength increased to 577 MPa, which is the maximum compressive strength in this study. On the other hand, with 6 wt% and 9 wt% Cu addition, the compressive strength became 140 MPa and 201 MPa, respectively. A Ti-10Mo alloy with a 3 wt% copper content was able to achieve the maximum hardness of 576 HV. In short, the addition of 3 wt% copper successfully increased the compressive strength as well as the hardness of the prepared titanium alloys.

“…Alloys based on TiNi are widely used in various fields of technology and medicine. This is due to their unique functional properties, shape-memory effects and super elasticity, as well as a high level of biocompatibility [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ]. The latter is ensured by their corrosion resistivity and electrochemical passivity of the superficial oxide layer composed of TiO 2 [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ].…”

Alloys based on TiNi are widely used in various fields of technology and medicine. In the present work, we report on the preparation of TiNi-alloy-based wire with the shape-memory effect, which was used for compression clips for surgery. The composition and structure of the wire and its martensitic and physical–chemical properties were studied using SEM, TEM, optic microscopy, profilometry, mechanical tests, etc. The TiNi alloy was found to consist of B2 and B19’ and secondary-phase particles of Ti2Ni, TiNi3 and Ti3Ni4. Its matrix was slightly enriched in Ni (50.3 at.% of Ni). A homogeneous grain structure was revealed (an average grain size of 19 ± 0.3 μm) with equal quantities of grain boundaries of special and general types. The surface oxide layer provides improved biocompatibility and promotes the adhesion of protein molecules. Overall, the obtained TiNi wire was concluded to exhibit martensitic, physical and mechanical properties suitable for its use as an implant material. The wire was then used for manufacturing compression clips with the shape-memory effect and applied in surgery. The medical experiment that involved 46 children demonstrated that the use of such clips in children with double-barreled enterostomies permitted improvement in the results of surgical treatment.
