Summary: Boron carbide (B4C) particle reinforced aluminum (Al) matrix composites have wide applications due to their high modulus, high strength, low density, excellent wear resistance, and good neutron absorption. Introducing nano-scale reinforcements into the composites can improve the strength-ductility matching. This study successfully fabricated B4C/SiC/Al composites with different volume fractions of SiC nanowires and achieved improved strength-ductility matching compared to B4C/Al composites.

Summary: The aluminum nanocomposite with CNT and SiC/B4C powder reinforcement was fabricated using the squeeze stir casting method. The distribution of reinforcement and phase analysis were confirmed by SEM and XRD. TEM analysis revealed the formation of intermetallic compounds, dislocation forests, and reinforcement-matrix interaction. Nano indentation tests showed that the addition of B4C increased the nano hardness, Vickers hardness, and Young's modulus compared to SiC. Surface topography analysis indicated that B4C reinforced composites had reduced stripping pits, wear width, and depth.

Summary: Boron carbide (B4C) ceramic composites with excellent mechanical properties were fabricated using B4C, silicon carbide (SiC), titanium boride (TiB2), and magnesium aluminum silicate (MAS) as raw materials. The influences of SiC and TiB2 content on the microstructural evolution and mechanical properties of the composites were investigated. MAS in the composites effectively removes oxide layers from ceramic particles during high temperature sintering. The toughening mechanism of the composites is mainly attributed to crack deflection along the grain boundary caused by thermal expansion mismatch between B4C and TiB2.

Summary: The study found that increasing SiC particles can improve the hardness and compressive strength of AZ91-Mg2Si composite, but may reduce compressive elongation. Wear tests results showed that more SiC particles contribute to enhanced wear properties. However, under the highest loads, extruded composite with large SiC particles exhibited weak wear resistance.

Summary: Organic-carbon-precursor-added B4C and B4C-SiC ceramics were pressureless sintered at various temperatures. The addition of a carbon precursor increased the densification of the ceramics, with the B4C-SiC composite achieving higher density than the B4C ceramic. The composite with 95 wt. % B4C, 5 wt. % SiC, and 7.5 wt. % carbon precursor sintered at 2200 degrees C exhibited excellent properties comparable to composites fabricated using other methods.

Summary: Reaction-bonded B4C-SiC composites show promising potential for advanced technological applications. The microstructure evolution mechanism of these composites was investigated by fabricating B4C-SiC composites through Si-melt infiltration. The mechanical properties, microstructure, and phase evolution were found to be influenced by sintering time and B4C content, with increasing temperature and time leading to reduced unreacted B4C and improved hardness.

Summary: This study aimed to manufacture Al6061 alloy, Al6061-B4C, and Al6061-B4C-graphene composites with varying contents of B4C and graphene using the induction heat treatment process and powder metallurgy route. The results showed that the addition of graphene/B4C and the induction heat treatment process improved the tribological and mechanical properties of Al6061 hybrid composites, including wear rate, mass loss, friction coefficient, compressive strength, hardness, density, and microstructure. The Al6061-30B(4)C-0.15-graphene composite, which was heat treated and sintered, exhibited the highest hardness (238 +/- 4 HV) and compressive strength (571 +/- 6 MPa), achieving approximately 150% and 126% increase compared to the Al6061 alloy.
