“…The base alloy’s strength is improved by the presence of B 4 C particles with an average particle size of 80–90 μm. B 4 C and Al matrix coefficient of thermal expansion difference is responsible for Al2011composite’s increased tensile strength . Expanding B 4 C in this way increases the dislocation density of the lattice material, providing a disengagement fortifying effect on the Al network.…”

Micron-sized B 4 C addition to the Al2011 alloy was investigated for its impact on mechanical and wear performance. The stir-casting method was used to manufacture the Al2011 alloy metal matrix composites reinforced with varying percentages of B 4 C particulates (2, 4, and 6). The microstructural, mechanical, and wear properties of the synthesized composites were tested. scanning electronic microscope (SEM) microscopy and XRD patterns were used to characterize the microstructure of the samples that were obtained. The XRD patterns confirmed the presence of B 4 C particles. The addition of B 4 C reinforcement increased the metal composite's hardness, tensile strength, and compressive strength. Incorporating the reinforcement resulted in a decrease in elongation for the Al2011 alloy composite. The wear behavior of the prepared samples was examined under various load and speed conditions. In terms of wear resistance, the microcomposites were far superior. SEM observations of the Al2011−B 4 C composites revealed numerous fracture and wear mechanisms.

“…The Al7010 amalgam with B 4 C composites is stronger as a result of the expansion in dislocation density. For composites made from aluminium alloys such as aluminium alloy Al7010, B 4 C is a good choice because it acts as a barrier to particle dispersion and as a reinforcement of the matrix, preventing separation and improving the quality of the composites [19].…”

In the current studies an investigations were made to know the effect of 20 to 25 micron sized B4C particles addition on the physical and mechanical behaviour of Al7010 alloy metal composites. Al7010 alloy with 4 and 8 wt.% of B4C composites were produced by stir cast process. These synthesized composites were tested for numerous mechanical properties like hardness and tensile behaviour along with density measurements. Further, microstructural characterization was carried by SEM and XRD analysis to know the micron sized particles distribution and phases. By adding 20 to 25 micron sized B4C particles hardness and tensile strength of Al7010 alloy was enriched with slight decrease in elongation. Further, density of Al7010 alloy was decreased with the accumulation of B4C particles. Various tensile fracture behaviours were observed by SEM analysis.

“…Al2O3 and SiC ceramic particles are the most often utilized materials for aluminum reinforcement. Due to its great hardness it is the third hardest substance after diamond and boron nitride boron carbide (B4C) might be used as a replacement to silica and aluminum oxide [5]. High strength, low density, exceptionally high hardness, strong wear resistance, and good chemical stability are some of B4C's appealing qualities.…”

The influence of adding B4C particulates with a 40 and 90 µm sizes on the compressive strength, tensile strength and impact toughness of the A356 alloy is being studied. In the Al alloy matrix, 40 and 90 µm -sized micro B4C particulates are employed as reinforcements. In the A356 alloy, composites are created utilizing the liquid melt process in increments of 3 and 6 weight percent. Using an energy dispersive spectroscope (EDS) and a scanning electron microscope (SEM), samples are examined for microstructural characterization. According to ASTM standards, mechanical characteristics including tensile, hardness, compression, and toughness are assessed. The consistent distribution of B4C particles in the A356 alloy is seen in SEM micrographs, and this is supported by EDS analysis. Additionally, the inclusion of B4C reinforcement improves the compression and impact strength of the base matrix A356 alloy, which is especially noticeable in the case of reinforced composites that are 6 wt. % of 40 µm B4C in size.
