“…Reinforcing materials are usually added in matrix alloys to strengthen the final product. Several types of reinforcing particulates with various sizes like silicon carbide, aluminium oxide, titanium carbide, boron carbide etc., have already been used in developing composition materials so far [13]. Here, in the present work Boron Carbide (B4C) and Graphite (Gr) have been used as reinforcing agent in A356 alloy.…”

The current work gives the detailed microstructural analysis and wear behaviour of aluminium alloy A356 based metal matrix composite. Here, boron carbide (B4C) and graphite (Gr) particulates were used as reinforcing phase to develop A356/ 4 wt% B4C, A356/ 4 wt% Gr composites along with A356/ 4 wt% Gr/ 12 wt% B4C hybrid composites. The composites were developed by conventional stir casting method to improve the wear properties. The developed composites were subjected to scanning electron microscope (SEM) for microstructural analysis and then to DUCOM made wear test assembly to know the dry sliding wear behaviour. The wear tests were conducted for different loading conditions of 1, 2 and 3 kg for a sliding distance of 4000 m over the speed of 100, 200 and 300 rpm, respectively. The result show decreased wear upon addition of reinforcing particulates and SEM results of developed composites revealed utmost distribution of particulates. Wear morphology of worn surfaces were also carried out using SEM.

“…Furthermore, B4C, as like different fortresses strengthens the framework by creation of high-density disengagements in the midst of cooling to room temperature due to the qualification of coefficients of thermal extension improvements between the B4C and network AA2124 compound. Confound strains created between the support and the lattice deters the development of separations, bringing about progress of the hardness of the composites [13]. Mazahery et al [25] investigated the hardness behavior of A356 alloy with the nano SiC particles; it was found that hardness of A356-nano SiC composites is higher than that of the non-reinforced A356 alloy.…”

In the present investigation, the mechanical and wear properties of aerospace alloy AA2124-9 wt% of B4C composites were displayed. The composites containing 9 wt% of micro boron carbide in AA2124 alloy were synthesized by liquid metallurgy method through stir casting. For the composites, reinforcement particles were preheated to a temperature of 400℃ and afterward added in ventures of two stages into the vortex of liquid AA2124 alloy compound to improve the wettability and dispersion. Microstructural examination was carried out by SEM and elemental investigation was finished by EDS. Mechanical and wear properties of as cast AA2124 alloy and AA214-9 wt% of B4C composites were evaluated as per ASTM standards. Microstructural characterization by SEM and EDS confirmed the distribution and presence of micro boron carbide particles in the AA2124 alloy matrix. The hardness, ultimate strength, yield strength and bending behaviour of AA2124 alloy enhanced with the incorporation of 9 wt% of micro B4C particles. The hardness of as-cast AA2124 alloy was 65.76 BHN; it is 96.7 BHN in 9 wt% of B4C reinforced composites. The ultimate and yield strength of AA2124 alloy was 187.08 MPa and 150.33 MPa respectively. The enhanced UTS and YS in 9 wt% of B4C reinforced composites were 254.1 MPa and 203.7 MPa, respectively. Further, ductility of AA2124 alloy decreased with the presence of B4C particles. Wear resistance of aerospace alloy increased with the addition of micro particles. Tensile fractography and worn surface morphology were studied on the tested samples to know the various fractured and wear mechanisms.
