Aluminium matrix composites (AMCs) have great potential for critical applications within aerospace, automotive, defence, marine, agriculture and nuclear engineering sectors. The composite materials are very attractive because of their good balance between lightweight versus high strength and machinability. Depending on the particular application, these properties can be further enhanced by adding silicon carbide, boron carbide and graphite, respectively. These reinforcements help to upscale the physical/mechanical properties in order to meet the novel industrial demand. In the present work, a novel hybrid composite is developed through stir cast welding technique. The novel materials manufactured are of great importance, because they exhibit higher mechanical properties and better wear resistance with respect to classical materials (i.e. pure aluminium). The results of mechanical test showed that the addition of 5% boron carbide content to aluminium matrix permits to enhance the tensile properties, shear strength and hardness values; 6% silicon carbide and 4% graphite allow to improve the flexural strength and wear rate, respectively. The best performance was obtained for aluminium composite with 5 wt% boron carbide. The correlation between industrial requirements and the findings from this research indicates that the newly developed composite is an excellent candidate material for structural neutron absorber, armour plate and as a substrate material for computer hard discs.

In the present scenario, composites are in huge demand in the industries due to their light weight, wear resistance, stiffness and high strength. The functional and structural properties were improved according to the need of industry. Particulate reinforcement is one of the methods to enhance the strength, ductility and toughness of the composites. Stir casting or friction stir processing technique was used to fabricate the metal matrix composite. For technology seekers it is very difficult to select appropriate techniques because there is lack of bench mark standards and industry experiences. The novel contribution of this paper is to provide systematic approaches and methodology which enable academic user as well as industry persons to select appropriate method and parameters for the fabrication of the metal matrix composite. This study guides the new researchers to fabricate and characterize the mechanical properties of aluminium-based composites reinforced with Al2O3, B4C, SiC, TiC, graphite and TiB2 particles.

“…Al7075 alloy is one of the vital material used in aerospace and structural applications owing to its high strength and corrosion resistance. Selection of reinforcement is most vital part in the development of aluminum composites [6][7][8][9][10]. Reza et al, reported that the incorporation of nano alumina partciles into Al6061 matrix led to improvement in yield strength and ultimate strength of Al6061-Nano alumina composites [11].…”

In present study, Al7075-Beryl synthesized by using a stir casting technique. The different weight percentage of Beryl incorporated are 2Wt.% to 8 Wt.% in steps of 2 Wt.%. The effect of Beryl particles integration on hardness and tensile strength response on Al7075 were investigated. It is demonstrated that Beryl particles distributed homogeneously in the Al7075 matrix acts as effective reinforcement to enhance the mechanical properites. Compared to base Al7075 matrix, Al7075- 6 wt.% Beryl composites exhibited higher yield strength of 47.42%, ultimate tensile strength of 44.08% and Al7075-8Wt.% enhancement in hardness of 27.71% when compared to momlithic Al7075. As cast Al7075 alloy and Al7075-Beryl composites were microstructurally characterized with scanning electron microscopy (SEM), Energy dispersive spectrum (EDS) and X-ray diffraction (XRD). Microstructure study through scanning electron microscope study reveals that the uniform distribution reinforcement Beryl into Al7075 matrix. The Al7075- Beryl.
