“…This reason has resulted in various research into the machinability studies of AMCs. Research has shown that the presence of the hard-reinforcing particles incorporated into the aluminium alloy matrix while improving the properties of the composite, increases the difficulty in machining the said composites [11,12]. Such difficulties include increased surface roughness, increased tool wear, and increased cutting temperature.…”

Machinability studies of aluminium matrix composites (AMCs) is a necessary investigation required to understand their behaviour during machining to produce components effectively and efficiently. This established need has led to the investigation into the machinability of AA 6082 reinforced with 2.5 wt.% fly ash and 2.5 wt.% carbonized eggshell fabricated via stir casting. The studied machinability indices were material removal rate (MRR), cutting temperature, built-up edges (BUE) formation and chip morphology while the selected inputs were cutting speed (100 mm/min, 200 mm/min, 300 mm/min), feed (0.1 mm/rev, 0.2 mm/rev, 0.3 mm/rev) and depth of cut (0.5 mm, 1 mm, 1.5 mm). For the experimental design, the L9 orthogonal array was preferred to create 9 experimental runs. The analysis of the built-up edges showed that it increased at lower cutting speeds and increased feed and depth of cut. The examination of the produced chips after each experimental run showed the presence of c-shaped, helically shaped and ribbon-shaped chips. The analysis of variance (ANOVA) for both MRR and cutting temperature indicated that the depth of cut was the most influential factor on both responses. Multi-objective optimization using desirability function analysis showed that the optimum combination of parameters was 300 mm/min, 0.2 mm/rev and 1.0 mm for the cutting speed, feed and depth of cut respectively. The ANOVA of the composite desirability indicated that the cutting speed was the most contributing factor.

“…The characteristics include: hardness, corrosion resistance, wear resistance and thermal resistance. Thanks to their greater hardness than that of the matrix material, aluminium composites are regarded to be more difficult to machine than the matrix alone because of the blade wear index [1][2][3]. Another major index of material machinability is the cutting force.…”

This paper presents the results of experimental tests of the turning of an aluminium composite reinforced with Al2O3 fibres. The tests were carried out using three cutting tools with no cutting fluid and in minimum quantity lubrication (MQL) conditions. The cutting forces were measured. For further analyses the main force component was selected. Its mean values and amplitudes were calculated. Then the registered traces were filtered with Daubechies wavelets. Load constancy factors for the filtered off signals were calculated and compared with the factors calculated from the unfiltered signals. On the basis of this comparison, the level of disturbances and noise during the turning of the aluminium composites was assessed and the effect of the machining conditions on the size of the disturbances was determined. It has been found that the discrete wavelet transform can be a tool aiding the monitoring of the turning of composites.

“…Shape of the reinforcement may be fiber, particulate or whiskers type; fiber and particulates are most commonly used shape of the reinforcement. A proper selection of matrix & reinforcement and shape of the reinforcement is highly desirable for property improvement of the composite [7][8][9]. In recent years, aluminium and its alloys are most widely used non-ferrous metals and getting more popularity due to its high strength to weight ratio, easy to fabricate, and low production cost [10,11,12].…”

In recent years, aluminium and its hybrid composites receiving more attention due to its excellent property combinations like improved mechanical properties, better wear and high corrosion resistance, ease to process and probably reduced production cost etc.. Composite is made of two phases one is matrix and another one is reinforcement. The performance of composite highly depends on some key factors that decide overall performance and they are properties of constituent phases, reinforcement size, reinforcement distribution in the matrix and their interfacial interaction. Particle reinforced metal matrix composites (particulate metal matrix composites- PMMCs) are becoming more popular due to their low cost, easy to process and compatible to conventional processing techniques. Also they give isotropic properties. The most commonly used reinforcements are carbides, oxides and nitrides. A lot of research has taken place including carbide and oxide as a reinforcement particles for aluminum matrix composites (AMCs) and hybrid aluminium matrix composites (HAMCs) while there is a bit research lag in use of nitride as a reinforcement for development of AMCs and HAMCs. Recent competitive market demands the material having better combination of properties, cost effectiveness and eco-friendly nature. Present article focused on to study the microstructural features, physical properties, mechanical and tribological behavior of aluminium matrix composites when reinforced with silicon nitride particles (Si3N4). Potential area of applications has also been suggested on the basis of literature data. In this review a comprehensive study has done for current scientific development carried out in Al based Si3N4 composites as well as its future scope has also been discussed
