“…With increase in more number of reinforcements than there is high possibility that these are placed quite closely to each other due to which the indenter finds it difficult to cause large plastic deformation. A closer look on the work reported by Javdani and Daei-sorkhabi [36] explains that the result presented by the current work is well in line with that reported by these authors. In their work the authors claimed that the increase in hardness value of Al7075/B 4 C composite was attributed to uniform dispersion of B 4 C particles.…”

In the present work, Al7075 based hybrid composites was developed using stir casting technique. Al7075 hybrid composites with different weight percentage of Mica, Graphite and E-glass fiber were developed to study the effect of these reinforcements on microstructure and mechanical properties, E-Glass fiber is kept constant at 0, 2, 4%, Mica is varied from 1-3% in steps of 1 and Graphite varied from 1-5% in steps of 2. It can be seen that the three peaks corresponding to Al were seen at 38º, 46º and 65º 2θ angles and small peaks related to all the three reinforcement mica, graphite and E-glass fiber were observed in the XRD pattern. Grain size analysis was examined using Clemex Image-Analyzer software, it was observed that decrease in grain size of Al7075 matrix was found to decrease with the increase in reinforcements, Hardness was found to increase with increase in reinforcement content whether it could E-glass fiber from 0% - 4% or mica from 1% - 3% or graphite content from 1% - 5%. Ultimate tensile strength increased with the increase in reinforcement content both before and after heat treatment.

“…The two or more materials namely "Matrix" and "Reinforcement" having different physical and chemical properties when mixed in a way that neither they fully fuse nor liquefy into one another, so despite they act jointly but remain dispersed are called composite [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Composites are mainly categorized into three groups as 1) Ceramic Matrix Composites (CMCs), a subgroup that consists of ceramic matrix and ceramic fibers [19][20][21][22][23][24][25][26]. As compared to old-style composites CMCs show tremendous improvement in fracture toughness, ductility, and thermal shock resistance.…”

Commercialization of the developed technology is a prime factor for any nation and sector to retain its existence in this global economy. Day by day the technological advancement touching new high in various sectors like the automobile and aircraft industries but high design efficiency is achieved only when it is complemented by appropriate material. In the list newer addition is MMCs (Metal Matrix Composites) which are favorable because of their lower cost achieved by cheaper reinforcement, easy processing, and capabilities of mass production. In recent days, the importance of semi-solid casting has been well accepted among various processing routes for aluminum alloys despite many challenges in terms of process parameters like porosity, agglomeration, non-uniform reinforcement particle distribution, low wettability, and engulfment, and this is a main consideration for the present work. Semi-solid casting is considered to be one of the most important and effective manufacturing processes of aluminum alloy for viable mechanical and metallurgical properties in the current perspective of product requirement and competitiveness. A glimpse of the current status is presented, which shows the potential of the process which can be utilized by the industries for several benefits. In a nutshell, it can be found that process has the capability of alteration by the use of different scraps and also have flexibility according to the processing parameters like stirring, pouring temperature, type of reinforcements, etc.

“…It has been confirmed that metal matrix composites (MMCs) can offer outstanding mechanical properties and superior wear resistance [3−5]. The alloys reinforced by particulates, such as SiC [6], TiB2 [7], WS2 [8], B4C [9] and Al2O3 [10], have been used in various applications. The introduction of particulates into a single-phase matrix of HEA/MEAs can be an effective approach to improve mechanical properties, in particular the wear resistance.…”
