“…12 Further, the hybrid composite was prepared by the squeeze infiltration method. The flexural strength has been improved by 29% due to the incorporation of Mg 2 B 2 O 5 and B 4 C p hybrid reinforcements in the Mg matrix as reported by Li et al 13 Chen and Yao 14 enhanced the wettability between matrix and reinforcement in the metal melt infiltration composite manufacturing process by the addition of metal powder in ceramic preform with a higher melting point. Researchers reported that the addition of ceramic particles reduced the wear rate.…”

In this study, magnesium–boron carbide composites are developed through the powder metallurgy technique and investigated for their tribological properties using a pin-on-disc tribometer. The process parameters such as load, sliding distance, sliding velocity, and concentration (wt%) of boron carbide are optimized using Taguchi's L16 array. A lower wear rate of magnesium–boron carbide composite is obtained at optimized process parameters. Further, the analysis of variance result shows that the most dominating factor that affects the wear loss is load followed by concentration of boron carbide reinforcement. Moreover, the optimum parameters for the low wear rate of magnesium–boron carbide composites are obtained as 5 N, 6 wt% of boron carbide, 1200 m, and 3 m/s through signal-to-noise ratio analysis. Further, the mechanical properties of magnesium–boron carbide composites such as hardness and compressive strength are also analyzed. The result shows that the hardness and compressive strength of magnesium–boron carbide composites are improved with the inclusion of boron carbide reinforcement.

“…Figure 2 illustrates the schematic diagram of squeeze casting to fabricate (Mg 2 B 2 O 5w ?

In the last two decades, lightweight magnesium matrix composites have been the hot issue of material field due to their excellent mechanical and physical properties, e.g., high-specific strength and modulus, good wear resistance, and damping capacity. As compared with aluminum matrix composites, magnesium matrix composites have merit in their specific weight and have wide applications in aerospace and aeronautical fields. Generally, the processing techniques for magnesium matrix composites can be categorized as conventional and special processing routes. In recent years, as a special processing route, metal melt infiltration into porous ceramic preform featured by its low cost and availability of high-volume fraction of reinforced ceramics have been receiving much attention. Thus, in this review, one emphasis was put on the description of this processing technique in association with the means to obtain good wettability, the prerequisite for this kind of processing method. Based on the recognized fact that there exist clean interface and bonding ability between ceramics and matrix metal, in-situ reaction synthesis is usually utilized to fabricate magnesium matrix composites. Therefore, the interfacial feature was also reviewed for the in-situ reaction synthesis. Characterizations of microstructures and various mechanical-physical properties were finally summarized for magnesium matrix composites including tensile response, wear resistance, creep behavior, and damping capacity.

“…3 MMCs can be reinforced by the different reinforcements, such as ceramic particle, whisker, fiber, carbon nanotube, and so on. 4–6 In recent years, among these MMCs, the ceramic particle-reinforced MMCs have attracted extensive research interests due to their excellent and isotropic mechanical properties, easy fabrication, and low cost. 7 Moreover, it is also expected that further improvements in room temperature and high temperature mechanical properties, and wear resistance of MMCs can be realized by the proper selection in type and size as well as volume fraction of the ceramic particle reinforcement.…”

Many interesting studies on composites with nano or submicron SiCp have been performed since the size advantages of fine SiC particles. However, it is extremely hard to disperse fine particles in metal melts due to their poor wettability and large surface-to-volume ratio, especially the fabrication of composites with multisized SiCp (5 µm, 0.5 µm, and ∼60 nm) is very difficult. The use of multisized reinforcements is required to solve the dispersion problem. The stir casting technology and hot extrusion method could be used to disperse the multisized SiCp in the matrix. The effects of multisized SiCp on the dynamic recrystallization behavior of the composites are discussed. The large-scale dynamic recrystallization caused by adding multisized SiCp results in a fine matrix microstructure. Compared with the as-accepted AZ31B alloy (YS: 195 MPa, UTS: 277 MPa), the yield strength and ultimate tensile strength of the AZ31B/SiCp/n-1 + S-4 + 5-10 composite were enhanced to 73.8 and 44.8%, respectively. The better tensile properties were attributed to the uniform distribution of reinforcement, strengthening effect of multisized SiCp, and grain reﬁnement of magnesium matrix.
