“…It was further identified that crack formation decreased the bonding strength of MMC reinforced with SiC and B 4 C particles. Sarada et al [12] analyzed the wear behavior of stir cast hybrid aluminum composite material. The properties such as hardness and wear resistance increased in case of hybrid composites, whereas it was not variable in case of single type of reinforced particles.…”

The efficient machining of metal matrix composite becomes important factor with respect to the high strength and hardness properties. The presented research work observes the influence of CO 2 laser processing parameters on various metal matrix composite materials in terms of material removal rate (MRR). A comparison has been explored between various composite materials such as silicon carbide (SiC), aluminum oxide (Al 2 O 3), and zirconium oxide (ZrO 2) metal matrix composites for MRR. This results in novel research in context of MRR that examines the microstructure of machined work material. In the present study, to determine MRR various weighing evaluations and topography of machined surface were studied. The results indicated that the focal position, cutting speed and reinforced particles are the significant parameters for MRR. The morphological and metallurgical changes such as formation of recast layer have been analyzed using scanning electron microscope. The chemical composition of machined work materials and formation of new compound have been identified using EDS/XRD technique.

“…One of the essential objectives is to develop an MMC material with a combination of mechanical and wear resistance properties. MMC possesses good mechanical properties, creep and wear-resistance when compared to aluminium alloy [4]. Al6061 is widely used for structural fabrication applications due to its reliable strength, weldability, and corrosion resistance [3].…”

Owing to its outstanding mechanical and thermal properties, graphene has shown enormous potentials as an improvement material for composites. This paper investigates the properties of graphene-reinforced 6061 aluminium alloy Metal Matrix Composites (MMCs) with varying weight percentages (5 and 10 wt.% graphene) of reinforcement. Energy Dispersive Spectroscopy (EDS) and Scanning Electron Microscope (SEM) studies of the MMC confirm the presence and distribution of graphene particles in the Al6061 matrix materials. Mechanical properties such as tensile strength, hardness, and impact strength of MMCs were studied and assessed. Tensile and impact strength of the MMC's increased from 25 to 60 % by the addition of 10 wt.% graphene in aluminium 6061 alloys. The percentage of elongation diminished with the addition of reinforcement in the matrix. The most significant improvement in hardness can be found in additional graphene particles. Wear-test had been performed using the pin-on-disc machine at 10 N load. It was observed that the tribological behaviour of the composite improved after the addition of graphene in Al6061.

“…Owing to its light weight, good corrosion resistance, castability and excellent thermal properties these composites are gaining wide popularity as high performance material. Aluminum based hybrid composites shows improved primary and secondary properties over conventional base alloy [2,3]. Ceramic materials generally used to tailor the desirable properties of Al alloys are SiC, TiC, TiB 2 , ZrB 2 , AlN, Si 3 N 4 , Al 2 O 3 and SiO 2 .…”

The demand of high quality casting with good performance, lightweight materials is being increased in automotive and aircraft industrial applications to achieve fuel economy. Application of the metallic chills with high volumetric heat capacity is one of the primary method to develop required sound quality casings. In the present research work LM 13 aluminum alloy matrix hybrid composites having 3 to 12wt% of garnet in steps of 3wt% and constant 3wt% of Carbon are developed by using chills to improve directional solidification. Experimental investigations are carried out to study the effect of chilling on microstructure, dry sliding wear and sand abrasion behavior of the composite samples. Copper, steel, iron metallic and silicon carbide nonmetallic chills were used to study the tribological behavior of the samples and compared the same with non-chill cast specimens. ASTM standard specimens taken from chill end of the casting were tested for tribological behavior.
