“…This was reported by Kondoh et al [24], whose work confirmed the improvement in tensile strength, yield strength, microhardness and strain of commercially pure titanium by the incorporation of MWCNT as reinforcement phase. Similarly, Sun et al [25] recorded an improvement in ultimate tensile strength and hardness of titanium by reinforcing it with MWCNT. Additionally, Munir et al [13] realized an improvement in the mechanical and tribological properties of titanium by the integration of MWCNT into its matrix.…”

In this study, the role of multiwall carbon nanotubes (MWCNT) on the microstructural evolution and mechanical properties of Ti6Al4V-based composites was investigated. This was conducted by dispersing different concentrations (0.5, 1.0 and 1.5 wt%) of MWCNT into the Ti6Al4V matrix using shift-speed ball milling technique. Thereafter, the Ti6Al4V and the nanocomposites were consolidated via the spark plasma sintering technique. Various characterization techniques; scanning electron microscopy (SEM), transmission electron microscopy (TEM) and light microscopy were conducted to understand the microstructural evolution of the samples after the dispersion and sintering process. Subsequently, micromechanical and nanoindentation was carried out to reveal the mechanical properties of the fabricated samples. The morphological examination using SEM and TEM revealed the dispersibility of MWCNT dispersed within the Ti6Al4V matrix. Besides, the selected area diffraction and the fast Fourier Transform pattern demonstrated that the increase in concentration of the MWCNT exposed the nanotubes to adverse stresses during the dispersion process. Furthermore, the incorporation and increase in concentration of the MWCNT in the titanium alloy resulted in microstructural and phase changes, which translate to tremendous improvements in microhardness, nanohardness and elastic modulus up to 46.9%, 150.8%, and 169.5% respectively.

“…[21][22][23][24][25][26] Carbide materials can be synthesized on CNT supports through precursor method and in situ thermal reduction, during which the covalent bond is formed between metal and carbon. [27][28][29][30][31][32] Up to now, many CNT/TiC based bulk electrodes have been demonstrated and showed excellent electrochemical performances. For example, TiC hollow ber-CNT integrated electrodes obtained by carbothermal treatment was reported by Xia et al with a high capacitance of 185 F g À1 and stable cycling life.…”

“…Research has found that an exothermic reaction between Fe and Ti 3 AlC 2 is predominant above 763.1 °C, and Ti 3 AlC 2 totally disappears and transfers into TiC x and Fe (Al) when the temperature is up to 1045 °C [ 24 ]. Furthermore, TiC x is also a commonly used reinforcement agent in IMCs and has a good reinforcing effect for metal matrix composites (such as titanium [ 27 ], high entropy alloys [ 28 , 29 ], and iron [ 30 ]), as it has excellent hardness, a high melting temperature (3147 °C), wear resistance, and thermodynamic stability, according to previous work [ 8 ]. Meanwhile, it is predicted that there is better interface bonding between the matrix and TiC x that is formed by the decomposition of Ti 3 AlC 2 .…”

Ceramic-particle-reinforced iron matrix composites (CPR-IMCs) have been used in many fields due to their excellent performance. In this study, using the fast resistance-sintering technology developed by our team, iron matrix composites (IMCs) reinforced by both SiC and TiCx particles were fabricated via the addition of SiC and Ti3AlC2 particles, and the resulting relative densities of the sintering products were up to 98%. The XRD and EDS analyses confirmed the in situ formation of the TiCx from the decomposition of Ti3AlC2 during sintering. A significant hybrid reinforcing effect was discovered in the (SiC + TiCx)p/Fe composites, where the experimental strength and hardness of the (SiC + TiCx)p/Fe composites were higher than the composites of monolithic SiCp/Fe and (TiCx)p/Fe. While, under the condition of constant particle content, the elongation of the samples reinforced using TiCx was the best, those reinforced by SiC was the lowest, and those reinforced by (SiC + TiCx) fell in between, which means the plastic response of (SiC + TiCx)p/Fe composites obeyed the rule of mixture. The successful preparation of IMCs based on the hybrid reinforcement mechanism provides an idea for the optimization of IMCs.
