“…The TiC particle presents a much higher hardness compared to the matrix alloy. This indicates the TiC particle enhances the resistance to mechanical damage and wear [51]. The Fe-TiC composite may also be produced under this condition with iron oxide particles from the ball.…”

Hot rolling of titanium alloy currently is carried out without lubrication because of the surface defects. In order to explore an effective lubrication scheme to reduce friction and wear during hot rolling of titanium alloy, a mixed graphene-incorporating lubricant has been proposed to study its lubrication performance and mechanism. The tribological experiments were carried out by ball-disk friction and wear tester under hot-rolling parameters. Scanning electron microscopy (SEM), X-ray energy spectrum analyzer (EDS), X-ray powder diffractometer (XRD) and Raman analysis were used to analyse the surface and cross-section of the wear marks on the samples after the tribological experiments. The results show that the friction coefficient decreases up to about 35% compared with tests under dry and lubricated conditions. The surface quality of the wear marks is improved significantly after applying the proposed lubricant. The graphene which is embedded in the phosphate film can be effectively applied as a lubricating material to strengthen the lubricating film with less combustion loss at high temperatures. A chemical- and mechanical-induced lubrication mechanism for the hot rolling of titanium sheets has been proposed due to the synergistic lubrication effect of the graphene, ZrO2 nano particles and phosphate. It is of great significance and potential value to apply this proposed lubricant as an effective way to reduce the wear, friction and oxidation during the hot-rolling process of titanium alloy.

“…The measured average volume fraction of TiC obtained using ten lowmagni cation SEM images was approximately 58%. The observed TiC reinforcements in the SS431 matrix had relatively round shapes compared with the as-received TiC particles because of the partial dissolution and reprecipitation of TiC [28,29] . In addition, the TiC-SS431 sample images showed that the TiC preform did not break and maintained its shape during the in ltration process.…”

“…Although MMCs are promising materials for the chemical and process industries, little attention has been paid to their properties owing to their high melting temperature, poor wettability, and density mismatch between the reinforcement and metal matrix [10,17] . Typically, steel matrix composites are reinforced with ceramic particles, such as carbides (titanium carbide (TiC), SiC, WC), borides (TiB 2 ), and oxides (Al 2 O 3 , ZrO 2 ) [18][19][20][21][22][23][24][25][26][27][28][29] . TiC particles can be considered as suitable reinforcements for steel matrix composites owing to their high hardness, low density, good wettability with steel, chemical inertness, and high melting point [23][24][25][26][27][28][29][30] .…”

The high-temperature properties such as the tensile strength, hardness, coefficient of thermal expansion (CTE), and thermal conductivity of titanium carbide (TiC)-reinforced stainless steel (SS) matrix composites fabricated by the infiltration process were investigated at various temperatures. Highly concentrated, closely adjacent TiC particulate reinforcement effectively suppressed dramatic variations in the CTE and thermal conductivity properties originating from the phase transformation of the SS431 matrix with superior mechanical properties. The strengthening effect of the addition of TiC increased as the temperature increased and showed a higher value after the phase transformation. The TiC–SS431 composite showed great applicability for advanced high-temperature-resistant structural materials.

“…Ceramic reinforcements have been added to the steel-based matrix to improve the mechanical properties. Among the reinforcement materials, a TiC-Fe metal-matrix composite shows superior mechanical properties such as high strength and hardness [18,19], good oxidation and wear resistance [20], and low density [21] compared with normal metal materials. While the mechanical properties of TiC-Fe composites are widely known, the dynamic properties of composites have not been systematically investigated.…”

The generation of machine tool spindle vibration is becoming prevalent as high-speed machining and lightweight design are being actively applied in the machining process. As the required machining accuracy increases, the machine tool spindle vibration generated in ultra-precision machining is the main cause of the deterioration of the machining quality. In this study, a TiC-SKH51 metal-matrix composite was used to suppress the machine tool spindle vibration. A vibration characteristic test was conducted to obtain the dynamic characteristics of the TiC-SKH51 and other testing materials. By comparing the results of the vibration characteristic test, the reliability of the finite element analysis software was confirmed. Then, dynamic and static analyses were performed to obtain the dynamic and static characteristics of the machine tool spindle model. The analysis results show that the TiC-SKH51 machine tool spindle can directly suppress the generation of spindle vibrations.
