“…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.…”

“…In this study, the material of the machine tool spindle was changed to a TiC-SKH51 metal-matrix composite, containing titanium carbide (TiC) reinforcement particles, to overcome the shortcomings of the existing methods. Including a gray cast iron and other metal materials, a vibration characteristic test was carried out to obtain dynamic characteristics of the TiC-SKH51 composite, which was fabricated via the liquid pressing infiltration method [18,19]. These results were compared with those of the FEA to confirm the accuracy of the analysis software.…”

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.

“…In MMC, the ceramic particle reinforced metal matrix has good mechanical properties and wear resistance and has been widely studied [5]. Among many particle reinforcements, titanium carbide (TiC) was considered to be a good reinforcement due to its high hardness, high melting point, and relatively high thermal and chemical stability [6][7][8][9][10][11]. There are two methods for prepared the TiC particles reinforced metal matrix by self-propagating high temperature synthesis (SHS) and additive particles.…”

In this paper, TiC particle reinforced high chromium cast iron matrix composites were prepared in situ by casting and infiltration method. The effects of different volume fractions of moderator on the size of reinforced particles, volume fractions of reinforced particles, hardness of composites and abrasive wear were studied. The results show that the TiC particles become smaller and more uniform with the increase of the volume fraction of moderator, and the volume fraction of the enhanced particles also decreases with the increase of the volume fraction of moderator. The hardness of TiC increased by 69%. Abrasive wear tests show that the abrasive wear resistance of the composite with moderator content of 20% is the best, the lowest wear rate can reach 2.011E-008,and the wear resistance is 1.8 times higher than that of the metal matrix.

“…However, composites fabricated by only spontaneous infiltration process have partially non-infiltrated pores between reinforcements and the matrix. There have been some studies to solve this problem, including the removal of non-infiltrated pores through an additional gas pressurization process [18,19].…”

This study was conducted on titanium diboride (TiB2) reinforced Al metal matrix composites (MMCs) with improved properties using a TiB2 and aluminum (Al) 1050 alloy. Al composites reinforced with fine TiB2 at volume ratios of more than 60% were successfully fabricated via the liquid pressing infiltration (LPI) process, which can be used to apply gas pressure at a high temperature. The microstructure of the TiB2–Al composite fabricated at 1000 °C with pressurization of 10 bar for 1 h showed that molten Al effectively infiltrated into the high volume-fraction TiB2 preform due to the improved wettability and external gas pressurization. In addition, the interface of TiB2 and Al not only had no cracks or pores but also had no brittle intermetallic compounds. In conclusion, TiB2–Al composite, which has a sound microstructure without defects, has improved mechanical properties, such as hardness and strength, due to effective load transfer from the Al matrix to the fine TiB2 reinforcement.
