“…The hardness results are in accordance with the behavior observed by previous investigations where the titanium increase had a positive effect on the hardness value, especially in values higher than 5% [8,42,48]. The studies carried out by Akbarpour et al [20] present a close reference to the hardness values found in the composites, despite the need for an aging process in order to promote intermetallic growth and the elimination of the thermal stress of the sintering to the extent that ideal values proposed by Shon et al [49]. Finally, despite the observations of pores at 850°C had been observed that their presence does not significantly deteriorate the hardness of the study system as pointed out by Zhao et al [50].…”

Microstructure and tribological properties had been studied in a Cu-Ti-1%TiC MMC with titanium concentration of 10%, 15%, and 20%. The composite was manufactured following the pulvimetallurgical route that included: mechanical and ultrasonic mixing in 2-propanol, compaction at 400 MPa and sintering assisted by abnormal glow discharge in an atmosphere of 10% nitrogen and 90% argon. The discharge was established in the direct current regime and the voltage values were adjusted according to the sintering temperatures of 750°C and 850°C. The sintering process was carried out for 30 min and then cooled in the same atmosphere. As a result, a differentiated in morphology and wear properties were obtained in the sintered parts. At 750°C a microstructure characterized by the stability of Ti grains with intermetallic precipitates such as CuTi 2 and CuTi were observed at the interface with the matrix. On the other hand, the intermetallic phases as Cu 3 Ti, Cu 4 Ti and CuTi 2 had been detected in the sintered at 850°C. These phases were related to diffusive processes that occurred during the sintering, enhanced by the energy provided by the process. It had been observed that with increase of titanium content an improvement of the MMC tribological properties. In titanium contents of 20% at 750°C was estimated a wear coefficient of 2.7 × 10 −8 mm 3 .N −1 .m −1 with a track width of 312 μm. Despite the pores originated during the sintering of MMC at 850°C was found a wear coefficient value of 2.4 × 10 −8 mm 3 .N −1 .m −1 and a track size of 778 μm, related to the plastic deformation exerted on the porous structures during the wear process. Results of the tribological analysis lead that this compound may be applied in fields where the balance between adequate tribological properties and lightness are highly required such as the automotive, aeronautical and biomedical industries.

This work reports the effect of TiC volume fractions on hardness of TiC/TiCu/C composites synthesized through in situ reactive infiltration of Ti-Cu alloy into porous carbon preforms prepared by 3 D-printing. Reactive melt infiltration of the alloy at 1100 °C under argon into C-preforms with different porosities resulted in materials composed of TiC, Cu-rich intermetallic matrix (Ti3Cu4) and residual carbon. The microstructure consists of TiC grains distributed along the Cu-Ti/C boundary. The hardness of TiC/Ti3Cu4/C composites could be tailored by the TiC volume fraction and the distribution in the composites, which are determined by the processing parameters and the initial porosity of the carbon templates in 3 D-printing stage. The hardness of the produced composites ranges from 350 HV to 570 HV and could be tailored by the TiC volume fraction and distribution in the composites, which are determined by the processing parameters and the initial porosity of the carbon-preforms.

“…Titanium–copper alloys and intermetallic compounds are advanced technological materials because of some attractive properties such as high electrical and thermal conductivity, a combination of strength, ductility and good fatigue resistance [1-6]. Apart from it, these alloys can find application as biomaterials since they exhibit high antibacterial activity, good cell biocompatibility and good mechanical, wear and friction properties playing a very important role in their clinical application [5-8].…”

Ti50Cu50 (at.-%) alloy has been produced from elemental Ti and Cu powders by high-energy ball milling in a planetary ball mill. Structural evolution of the alloy during milling and after subsequent heat treatment have been studied. It has been stated that high-energy ball milling of the investigated powder produces two nanocrystalline solid solutions: Cu(Ti) and Ti(Cu), both characterised by the fcc (Fm-3 m) structure. The transition of Ti structure from hcp (P63/mmc) to fcc (Fm-3 m) is observed during milling. Heat treatment of the milled powder leads to recrystallisation of Cu(Ti) and Ti(Cu) solid solutions. This paper is part of a Thematic Issue on The Crystallographic Aspects of Metallic Alloys.
