“…This is very intriguing in perspective of the perception made in the study that the fracture pursues a brittle process. The outcomes and the trends shown in the present case are like those obtained by different researchers [41], who likewise imparted the insight that the flexibility of the composite declines with increasing reinforcement. This loss in ductility can be credited to the embrittlement impact because of the hard SiC particles, which cause an increment in stress concentration sites.…”

In the current exploration, the impact of the 100 to 125 micron size addition of silicon carbide (SiC) on the mechanical performance of Al6061 alloy has been studied. The Al6061 alloy dispersed with 6, 9, and 12 wt.% of SiC particles were synthesized by a two-step stir cast route. Two-step addition of the preheated particles into the melt helps avoid the agglomeration of the particles, which further contributes to enhancing the properties of composites. The orchestrated composites were exposed to microstructural examines and mechanical properties evaluation. Microstructural portrayals of acquired examples were completed by SEM microscopy, EDS, and XRD patterns. The event of SiC particles were affirmed by the XRD patterns. The density of the Al6061-SiC composites was increased with the addition of high-density silicon carbide particles. The hardness, ultimate, and yield qualities of metal composites have been improved with the increase in the content of SiC support. The ductility of SiC reinforced composites decreased with hard ceramic particles' incorporation in the Al matrix alloy. Various fracture mechanisms were observed in the Al6061-SiC composites using SEM.

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.

“…As a result, materials have evolved into a picture of human progress and have progressed toward being achievements for separating periods of human history. B4C nanoparticles were supported to Zinc-compound composite using a liquid metallurgical course, in which the blending strategy was accomplished while pouring the particles to avoid agglomeration of particulates and to achieve a normal homogeneous dispersion of nano particulates in the molten [4,5].…”

The effect of nano-sized B4C particulates on the Zn85-Sn15 alloy has been investigated. Composites reinforced with B4C of (0%, 2%, 4% and 6%, by weight) are manufactured by two step stir casting. Microstructural studies carried out by SEM, EDS, and XRD and mechanical testing like tensile, hardness, and impact were performed on cast samples. The criteria for determining strength and fractography are met. EDS analysis confirms the homogeneous distribution of B4C particles in the Zn-Sn matrix seen in SEM micrographs. XRD examination revealed the B4C phases in the Zn-Sn alloy matrix as well. When B4C reinforcement is added to the basic matrix alloy, it improves its hardness and tensile strength with slight decrease in the ductility and impact strength. Further, tensile and impact fractured surfaces were studied to know the different fracture mechanisms.
