Hybrid Metal Matrix Composite

Aluminium 7075 widely used in aerospace and defence applications. At the present time, hybrid composite material utility is refining in all engineering areas as a result of high strength /weight ratio, good corrosive and wear resistance. In this research work deals with the fabricating of hybrid metal matrix composite of aluminium 7075 as base metal reinforced by varying weight percentage of Nano graphene (0.5,1,1.5,2) , B4C (2,4,6,8,) and Inconel alloy 625 (2,4,6,8). This boron carbide, Inconel alloy 625 particles having particle size of 50μm. The hybrid aluminium composite material fabricated utilizing liquid metallurgy ultrasonic stir casting method. Tension test, compression test, hardness test and flexural test were conducted to determine mechanical properties of the hybrid composite material. Morphology of the hybrid metal matrix composite were analysed by using SEM.

In present work, Aluminium 6061 was reinforced by varying the percentage of sugarcanebagasse ash (SCBA). Al-SCBA composite samples were fabricated by stir casting method. The weartest conducted on the samples using a pin on disc machine under the normal sliding condition. Basedon the testing parameters (Volume fraction ‘V’, Load ‘L’, sliding speed ‘S’) an L27 Orthogonal arraydesign was selected. According to L27 array, the wear & friction test was conducted. variance analysis(ANOVA) was performed to find out the important parameter and contribution in percentage for eachparameter on the composite material. To verify the analysis results with experimented resultconfirmation test was carried out. Further, to find the wear mechanism on the composite sampleselectron microscopy (SEM) test was used.

Hybrid Metal Matrix Composite

The composite material is a combination of two or more materials with different physical and chemical properties. The composite has superior characteristics than those individual components. A hybrid composite is the one which contains at least three materials. When the matrix material is a metal, the composite is termed as metal matrix composites (MMC). The MMC is a composite material with two constituent parts, one being a metal. The other material may be another metal, ceramic or fiber. Among all the MMC’s, Aluminium is the most widely used matrix material due to its light weight, high strength and hardness. This paper deals with the fabrication and mechanical investigation of hybrid metal matrix composite Al - SiC. The fabrication is done by stir casting by adding the required quantities of additives into the stirred molten Aluminium. The results show significant effect of mechanical properties such as tensile strength, yield stress and flexural strength. The internal structure of the composite is observed using Scanning electron microscope (SEM) and found that are formation of pores in them.

Lightweight engineering materials that are strong, durable, wear and corrosion resistant are required nowadays in the field of engineering, especially in the automobile industry. This study was to develop a hybrid composite material of palm kernel shell (PKS) and periwinkle shell (PS) particles as reinforcements in pure aluminium matrix. The central composite design (CCD) of the response surface methodology (RSM) was used to carry out the design of experiment (DoE). Stir casting method was used to fabricate the specimens. The DoE gave 20 runs (experimental samples) which were replicated three times each, bringing the total number of runs to 60 for each of the six responses considered, and 360 specimens were fabricated in all. Three experimental values were obtained for each of the 120 runs for the wear rate, creep rate, density, tensile strength, hardness and melting temperature. The average values were determined and recorded. Control specimens with 100 wt. % pure aluminium matrix, 0 wt. % of PKS and PS reinforcement particles were prepared. The results showed that the reinforcement particles had significant improvement on mechanical properties of the pure aluminium.

Todays composite material have gained more popularity due to their improved properties over the conventional materials. In the present paper, insitu composites were fabricated via chemical reaction between molten aluminium alloy and halide salt KBF4 with cryolite at 8000C by stir casting method. The microstructures of the composite containing 3 and 5 wt. % of AlB2 reinforcement phase have been compared with the unreinforced aluminium alloy. The microstructure analysis shows clean AlB2 particles uniformly distributed throughout the matrix. With the increase in the AlB2 reinforcement, insitu composite show less agglomeration and recovery of boron is more when compared to the unmixed halide salt in the fabrication of inistu composite
