“…For example, when B 4 C particles are used as the additives of TMCs, raw titanium powder can easily react with B 4 C particles during sintering, and then two phases of TiB w and TiC p (with subscripts w and p indicating whisker and particle, respectively) are synthesized and dispersed as the reinforcements in the matrix [24][25][26][27][28].

“…(2) The molten Ti-6Al-4V alloy matrix material due to high temperature instantaneously was redistributed and cooled on the machined surface. 20 The removal behavior of the ground PTMCs is rather complicated because it contains Ti-6Al-4V alloy matrix and the reinforcements, i.e. TiB whiskers, TiC particles.…”

TiC p + TiB w )/Ti-6Al-4V titanium matrix composites (PTMCs) have broad application prospects in the aviation and nuclear field. However, it is a typical difficult-to-cut material due to high hardness of the reinforcements, high strength and low thermal conductivity of Ti-6Al-4V alloy matrix. Grinding experiments with vitrified CBN wheels were conducted to analyze comparatively the grinding performance of PTMCs and Ti-6Al-4V alloy. Grinding force and force ratios, specific grinding energy, grinding temperature, surface roughness, ground surface appearance were discussed. The results show that the normal grinding force and the force ratios of PTMCs are much larger than that of Ti-6Al-4V alloy. Low depth of cut and high workpiece speed are generally beneficial to achieve the precision ground surface for PTMCs. The hard reinforcements of PTMCs are mainly removed in the ductile mode during grinding. However, the removal phenomenon of the reinforcements due to brittle fracture still exists, which contributes to the lower specific grinding energy and grinding temperature of PTMCs than Ti-6Al-4V alloy.

“…Relating to this, in-situ particle reinforced metal matrix composites (MMCs) exhibiting excellent mechanical properties owing to the formation of stable ceramic reinforcements during processing are reported in the literature including a wide range of matrix materials like titanium, aluminum, copper, nickel or iron along with borides, carbides, oxides and nitrides [5]. Especially with respect to the TMCs, investigations have shown that the most significant strengthening effect is achieved by reinforcement with titanium carbide particles (TiC) and whisker-shaped titanium boride particles (TiB) [6][7][8][9][10][11][12][13][14][15][16]. The high reactivity between titanium, boron and carbon at elevated temperatures enables the in-situ generation of the reinforcing particles through liquid-solid or solid-solid reactions during processing.…”

Abstract:In-situ TiB/TiC particle-reinforced titanium matrix composites (TMCs) based on a near-β Ti-5Al-5Mo-5V-3Cr alloy (Ti-5553) were synthesized by solid-state reaction with B 4 C and graphite particles during spark plasma sintering (SPS). In this study, investigations were focused on the influence of the molar TiB:TiC ratio on the mechanical properties of the composites. With respect to the adjustment of the molar TiB:TiC ratio, the formation of stoichiometric TiC or nonstoichiometric TiC y was considered as the literature provides conflicting information in this respect. Furthermore, the solid-state reaction behavior influenced by the matrix alloying elements is discussed in comparison to a pure titanium matrix. The hardness, compressive strength and bending strength of the TMCs were improved successfully due to the TiB and TiC particles maintaining acceptable levels of ductility. However, X-ray diffraction experiments revealed that for the adjustment of the molar TiB:TiC ratio, the stoichiometry of the TiC y particles formed must be considered as nonstoichiometric TiC 0.5 resulted from the solid-state reaction of carbon and titanium. Compared to TMCs with pure titanium matrices, more sluggish solid-state reaction kinetics were observed. This was attributed to the matrix alloying elements molybdenum, vanadium and chromium, which formed solid solutions within the reinforcing particles.
