“…The Young's modulus predicted by Gorsse et al [20] is around 120 GPa for 5 vol.% of TiB, about 6 % below the experimental value at RT obtained in this work. This difference can be attributed to the 0.1 wt.% of interstitial C added to the composite during its production.…”

“…In Figs. 2a-c, Ti64 reinforced with TiB shows a matrix with fine alpha grains, and two types of TiB precipitates in concordance with [20]: -Small TiB precipitates formed from the reaction Ti + B → TiB 2 followed by the reaction TiB 2 + Ti → 2TiB provoked by the excess of titanium. The mean cross section of these particles is around 0.4 µm 2 and the ratio feret max /feret min of about 10 (Fig.…”

Titanium grade 2, Ti-6Al-4V and Ti-6Al-6V-2Sn unreinforced and reinforced with 10-15 vol.% SiC particles, 5 vol.% TiB whiskers and 12-20 vol.% TiC are characterized by compression tests, micro-, macro-and nano-hardness measurements, and X-ray diffraction. The measured Young's moduli up to 350• C were found to be described using the Halpin Tsai model for the TiC and of TiB reinforced materials (aspect ratio of 1 and 100, respectively). The strengthening by SiC addition is attributed to matrix strain hardening due to the thermal misfit between the matrix and the reinforcement. The strengthening of TiC reinforced material is attributed to interstitial C dissolved in the alpha phase proved with the nanohardness results. TiB precipitates produce strengthening by grain refinement and dispersion hardening. The presence of 1 wt.% of C in the matrix also should be the reason for higher Young's modulus and strengthening.K e y w o r d s : metal-matrix composites (MMCs), mechanical properties, deformation, elastic properties, powder metallurgy

“…However, their widespread application has been restricted because of their low specific stiffness and wear resistance. In order to overcome this issue, titanium matrix composites (TMCs) using reinforcements such as TiB, TiC, or B 4 C have been developed (Panda, et al, 2003, Gorsse, et al, 2003, Melendez, et al, 2011, Kumar, et al, 2012, Liu, et al, 2009, Abderrazak, et al, 2011, Zadra, et al, 2014, Hulbert, et al, 2009, and Ni, et al, 2006. TiB as a reinforcement for Ti has several advantages compared with other reinforcements (Ravi Chandran, et al, 2002, andTamirisakandala, et al, 2006).…”

The effect of silicon, germanium, tin (X), and aluminum on the structure, physicochemical and mechanical properties of 8.5 at.% Al and 7.5 at.% B) quaternary alloys is studied by metallography, scanning electron microscopy (SEM), X-ray diffraction, differential thermal analysis (DTA), microhardness measurements, Vickers hardness measurements (from room temperature to 900°C), bending tests (room temperature), and compression tests (from room temperature to 700°C). The alloys are melted in an arc furnace from pure materials. Doping with p-elements (Al, Si, Ge, and Sn) does not change the specific titanium-boride eutectic structure in the two-phase (Ti) + TiB field. The doping additions hardly change the chemical composition of the eutectic and only decrease the boron content by 1-2 at.%. The Al, Si, Ge, and Sn (p-elements) are not soluble in TiB titanium borides and completely concentrate in the metal matrix in two-phase (Ti) + TiB alloys. The temperature of incipient sharp softening is shown to be exclusively connected with the matrix composition. It is determined that p-elements increase the hardness and strength of titanium-boride eutectic alloys in the entire temperature range of interest and increase the temperature of incipient sharp softening from 500 to 600-650°C. INTRODUCTIONTitanium monoboride (TiB) is a promising compound for reinforcement of titanium alloys and producing titanium-matrix composites. It is in thermodynamic equilibrium with the titanium-based phase characterized by low boron solubility. The boride and titanium phases have close thermal expansion coefficients and show favorable crystallographic coherency (the structure of the phases is shown in Table 1). Titanium boride is refractory and hard and has good wear resistance and high Young's modulus.Analysis of scientific publications of the last years shows that the number of papers focusing on titanium-matrix boride-reinforced composites increases. Test materials are mainly produced with powder metallurgy
