“…In aluminium composites, the properties like high toughness and ductility associated with aluminium matrix are combined with superior properties of ceramics such as high strength and elastic modulus by adding ceramic reinforcements in the base matrix [6], [7]. Alumina (Al 2 O 3 ), silicon carbide (SiC) and graphite (Gr) are the most common reinforcing materials [8], [9] which can be incorporated in the base aluminium matrix in the form of whiskers or particles.…”

“…Although the mixing time was the same, the particle distribution of B 4 C with 3.1 μm particle size and SiC with 4.8 μm particle size was not sufficiently homogenous. Small B 4 C and SiC particles caused to more agglomeration of the particles and hence, some agglomerated particles are observed in the matrix structure [1]. BUE creation was also seen at all machining parameters in the milling of AA7039/B 4 C and AA7039/SiC composites (Fig.5).…”

“…Many researchers are preferred the Al 2 O 3 , B 4 C and SiC particles as reinforcement element for their superior mechanical properties. On the other hand, the implementations of MMCs are restricted in a very specific industry due to high fabrication cost and their poor machinability [1][2][3]. Milling is one of the most common machining process for the desired form and size by removing material in industry.…”

Abstract-Metal matrix composites are used in many industrial fields such as automobile, military and aerospace applications due to their superior mechanical properties. In the present study, three aluminum 7039 metal matrix composite (MMCs) samples reinforced with 10 wt.% particulates of aluminum oxide (Al 2 O 3 ), 10 wt.% boron carbide (B 4 C), and 10 wt.% silicon carbide (SiC) were successfully fabricated using a powder metallurgy and hot extrusion method. The influences of cutting parameters on the thrust cutting force and torque during milling of the three MMCs were investigated under dry machining conditions. The milling tests were performed based on the Taguchi orthogonal -array design of experiments, for different machining parameters such as cutting speed, feed and depth of cut. The effect of reinforcement contents on cutting force and torque were specified by utilizing analysis of variance (ANOVA). Mathematical models have been generated for the thrust force and torque through regression method. The results indicated that the minimal thrust force and torque were obtained in the machining of the Al 2 O 3 reinforced specimen. The cutting force was directly influenced by the cutting feed and the axial cutting depth was the most effective machining parameter affecting milling torque in the machining of three composite specimens. The experimental results were modeled using regression analysis and artificial neural networks (ANN) to predict the thrust force and torque. The thrust force and torque were predicted with a mean squared error equal to 5.85% and 5.12% respectively using ANN models.

“…Several researchers have made extensive investigations in the relevant area. Some of the works done are, Senerkarabulut et al [1]conducted mechanical tests with AA7039with SiC, B4C, Al2O3as reinforcements, concluded with results showing elevated hardness, elongation, TRS, prolongation with Al2O3reinforced composite exhibited better bonding better surface. K. Umanath et al [2] studies are with A16061-T6, silicon carbide (SiC), aluminium oxide (Al2O3) composite on wear safety.…”

Investigations on mechanical behavior of Al7075 -nano B4C composites T H Manjunatha, Dr. Yadavalli Basavaraj, Madeva Nagaral et al. Abstract. MMCs are finding greater applications in aerospace, auto industries owing to their typical properties with respect to wear, mechanical and temperature resistance. The present study involves evaluation of microstructure, drilling, mechanical properties for Al7075 reinforced with Al2O3 content of wt.% 6.MMC and compare with Al7075 -6% B4C composite for showing effect of reinforcement on drilling, mechanical properties. The composite samples were examined for mechanical, bending strength, hardness, elongation behaviour. Results revealed that uniform circulation of particulates in matrix structure with great bonding. Al7075 reinforced with 6% B4Cdisplays high mechanical strength, better elongation, high surface quality and low hardness is seen. Surface roughness test was carried on the basis of Taguchi's L9 orthogonal, and analysed by ANOVA, results specify maximum influence on surface roughness is due to speed for Al2O3. Further with B4C the surface roughness is affected by material, confirmation tests were also conducted for validation of process parameters.
