“…The TiB volume fraction of all the composites processed through three powders metallurgical techniques (SPS, HIP and VS) is closer to the expected volume fraction with satisfactory deviation [16][17][18][19][20][21][22]. Be that as it may, the composites prepared through VS demonstrated some minimal varieties in density and TiB volume fraction from the theoretical values.…”

In this paper, the reciprocating wear behavior of titanium-titanium boride composites with 20 and 40 (by vol. %) titanium boride (TiB) particles IS investigated in dry sliding conditions against Al 2 O 3 ceramic balls. The trials have been observed at three loading conditions such as 5, 10 and 15 N load. The composites were processed by three powder metallurgical techniques such as spark plasma sintering (SPS), vacuum sintering (VS) and hot isostatic pressing (HIP). The electron probe microanalysis (EPMA) was used to analyze the homogeneity of Ti and boride phases in the composites. The hardness and indentation fracture resistance were evaluated using nano-indentation technique. The load-depth curves of indents for Ti-TiB shows the deviations of the modulus of elasticity within the spark plasma sintering (SPS), vacuum sintering (VS) and hot isostatic pressing (HIP).The wear resistance of the fabricated samples was analyzed using reciprocating wear tester. The SPS composite (Ti-38.5% TiB) showed lower coefficient of friction (0.07), lower wear volume (0.4368 mm 3) and wear rate (0.000276 mm 3 /m) when compared to HIP and VS, which is attributed to the presence of fine titanium boride needles of high hardness, contributing to improving wear resistance. The surface morphology reveals that the composites processed through spark plasma sintering (SPS) and hot isostatic pressing (HIP) are subjected to minor plastic deformation. The outcome of this work is more beneficial to automotive brake pad, precision manufacturing and locomotives to avoid critical wear failures.

“…It is worth noting that the thermal diffusivity of TMC-3 decreased slower than other TMCs, with the increase of temperature. That could be explained by the higher TiB thermal diffusivity than Ti [23] and they compensated for the thermal diffusivity decrease to some extent. The enhancement of thermal diffusivity of TiB to the Titanium matrix composites was reported by Selvakumar [23].…”

“…Differently, Yang [22] pointed out that graphene resulted in a degradation of thermal conductivity for the TMCs in the range of 0-0.4 wt% mainly because the addition of graphene led to an increase in grain boundaries and phase boundaries. M Selvakumar [23] proposed a strategy to improve the thermal conductivity of the TMCs by using reinforcements with higher conductivity, such as TiB. The maximum thermal conductivity reported by M Selvakumar [23] was as high as 55.74 W m −1 •w, however, the volume fraction of TiB reached 40 vol.%, which would deteriorate the mechanical property.…”

In this study, three titanium matrix composites (TMCs) reinforced with graphite, graphene, and boron carbide (B4C) were fabricated through powder metallurgical techniques. The morphologies of grains and secondary phases of these TMCs were observed through Optical Micrograph (OM) and Scanning Electron Microscopy (SEM). The results of the mechanical properties of the TMCs showed that B4C was the most effective in increasing the strength and hardness, while the strengthening effect was comparable between graphite and graphene. The plasticity of the graphene reinforced TMC decreased sharply because of the formation of strip-like agglomerations. The small sizes, large volume fraction, and uniform distribution of the secondary phases contributed to the enhancement of strength and hardness in boron carbide reinforced TMC. Although the thermal properties of the TMCs were lower than pure titanium in the temperature range of 25~300℃ , the thermal conductivities of the TMCs were all above 15.6W/m· K.

“…Titanium alloy is also one of the widely used light metal materials [57][58][59]. Conventional welding is employed to join titanium alloy and aluminum sheet materials together, but this joining technology damages the micro-structure of the welded region, adversely affecting the properties of the clinched joint.…”
