“…Almost full-dense AA2024/B 4 C composites with various B 4 C contents were produced by plasma activated sintering. Results showed that the B 4 C particles exhibit a network distribution in the composites with 7.5 wt% and 17.5 wt% B 4 C particles (Luo et al, 2017). Al356/5 vol.% SiCp cast composites were produced by the injection of reinforcement particles into the melt in three different forms, i.e.…”

Purpose Sound microstructure components are necessary for reliability and safety; hence, these components are used in aircraft, satellite, automobiles and ships, where many commercial alloys are not suitable. The paper aims to discuss this issue. Design/methodology/approach AA6082/Si3N4 and AA6082/SiC composites were fabricated using the stir-casting process considering 5, 10 and 15 vol.% of reinforcement particles. Density and porosity of AA6082/Si3N4 and AA6082/SiC composites were calculated. Characterization was done using an X-ray (EDX) detector, attached to SEM. The effect of addition of Si3N4 and SiC particulates in the AA6082 was investigated. Findings Results showed that Si3N4 and SiC particulates had good wettability with AA6082 and were uniformly distributed in AA6082 matrix. No adverse effects of reactions were noticed in the microstructure of AA6082/Si3N4 and AA6082/SiC composites. Research limitations/implications AA6082 with more than 15 vol.% of Si3N4 and AA6082/SiC reinforcement particles do not find industrial application where high hardness and tensile strength are required. Practical implications Components made from AA6082/Si3N4 and AA6082/SiC composites find their application where high hardness with better tensile strength is required. Social implications Naturally and locally available materials are utilized for fabrication. Originality/value Little work is available in the literature on fabrication and characterization of AA6082/Si3N4 and AA6082/SiC composites. The authors have identified the process parameters at which proper fabrication is done and sound microstructure is obtained.

“…Studies show that the hardness as well as the neutron cross section of the Al-B4C composite increases as the B4C ratio increases and the machinability of the composite decreases. [19][20][21][22][23]. Therefore, literature studies suggest Al-30%B4C composite as the ideal Al-B4C composite ratio.…”

This study aimed to calculate the thermal neutron (0.0253 eV) total macroscopic cross-section and gamma-ray (1.25 MeV) linear absorption coefficient for (100-x)Al-xGd2O3 (x=5 to 50) and 100-(x+y)Al-xGd2O3+yW (x,y=5 to 50) composites using MCNP6.2 simulation code. The simulation consists of a mono-energy point neutron and gamma-ray source, target material, and detector. The F4 tally from the MCNP6.2 library was used as the detector. The results show the highest thermal neutron total macroscopic cross-section for the 50%Al-50%Gd2O3 composite and the highest linear absorption coefficient for the 50%Al-%5Gd2O3-45%W composite. The results of this study provide a good understanding of the thermal neutron and gamma ray the shielding capabilities of Al matrix Gd2O3 and W doped composites.

“…The reinforcement of traditional B 4 C/metal composites is mainly B 4 C particles (B 4 C p ). Researchers have carried out structural design research on B 4 C p /Al and B 4 C p /Ti matrix composites by adjusting the volume fraction, morphology and dispersion of B 4 C. Luo and Zhang et al [ 8 , 9 ] found that increasing the B 4 C p content could effectively improve the properties, but when the mass fraction was 27.5%, B 4 C p agglomerated significantly, resulting in no further improvement in strength. Wu et al [ 10 ] found that when the volume fraction was fixed, the smaller the B 4 C p diameter, the higher the strength.…”

Composite material uses ceramic reinforcement to add to the metal matrix to obtain higher material properties. Structural design is an important direction of composite research. The reinforcement distribution of the core-shell structure has the unique advantages of strong continuity and uniform stress distribution. In this paper, a method of preparing boron carbide (B4C)-coated titanium (Ti) powder particles by ball milling and preparing core-shell B4C-reinforced Ti matrix composites by Spark Plasma Sintering was proposed. It can be seen that B4C coated on the surface of the spherical Ti powder to form a shell structure, and B4C had a certain continuity. Through X-ray diffraction characterization, it was found that B4C reacted with Ti to form layered phases of titanium boride (TiB) and titanium carbide (TiC). The compressive strength of the composite reached 1529.1 MPa, while maintaining a compressive strain rate of 5%. At the same time, conductivity and thermal conductivity were also characterized. The preparation process of the core-shell structure composites proposed in this paper has high feasibility and universality, and it is expected to be applied to other ceramic reinforcements. This result provides a reference for the design, preparation and performance research of core-shell composite materials.
