“…In addition, graphite, graphene, carbon nanotube (CNT) and hexagonal boron nitride (hBN) are commonly used solid lubricants in developing AMMCs. A. Gnanavelbabu et al investigated the cutting quality characteristics of AA6061-B 4 C-hBN hybrid composites by abrasive water jet machining and reported favourable results [6]. C. Muthazhagan et al found a positive influence of solid lubricant on the mechanical properties of aluminium-B 4 C composites.…”

Aluminium metal matrix composites have generated huge attention in modern industries because of its high strength-to-weight ratio, low density and corrosion resistance. Turning is a widely used material removal process to produce cylindrical products. Presence of solid lubricant reinforcements such as graphite (Gr), carbon nanotube (CNT) and hexagonal boron nitride (hBN) could increase the feasibility of turning on aluminium metal matrix composites. Aluminium alloy 6061 reinforced with B 4 C (5-15 vol.%) and hBN (10 vol.%) particulates were fabricated using stir casting process. The effect of process parameters such as feed, speed, depth of cut and volume percentage of boron carbide has been investigated to explore the impact on tangential force, cutting power and tool wear. Experiments were conducted using Taguchi's L 27 orthogonal array (OA). The factors affecting the responses were optimized by applying grey-response surface methodology (G-RSM) using grey relational grade (GRG) calculated by normalized S/N ratio and grey relational coefficient (GRC).

“…Gnanavelbabu et al machined hybrid aluminium composites (AA6061-B 4 C-hBN) using AWJM. The effect of factors like water pressure, AFR, mesh size and work traverse speed on KA and SR was analysed and reported that the water jet pressure and traverse speed were the most influential parameters in affecting the responses [22]. Pahuj et al carried out ABWJ machining of stacked titanium (Ti6Al4V) and CFRP using three pressure levels-200, 275 and 350 MPa.…”

Waspaloy is often used in aviation combustion chamber at extreme environments. Waspaloy is also a nickel-based superalloy with exceptional strength properties at a temperature of 980 °C. In this experimental investigation, waspaloy is used to analyse the kerf angle (KA), surface roughness (SR) and material removal rate (MRR) during abrasive water jet machining. The effect of various parameters such as traverse speed, abrasive flow rate, water pressure and stand-off distance on KA, MRR and SR was discussed. The striation formation was analysed for different set of process parameters. The striations were also analysed using atomic force microscopy. An attempt was done to relate the jet impinging angle and nature of striation formation. It was found that the increase in declination angle decreases the formation of striation during water jet process of waspaloy.

“…Quite a significant reserve for enhancing the strength is the further improvement of metal matrix composite properties, the development of their production technologies [11][12][13][14]. Not with standing, the cost of aluminum-based MMC is high and only single parts are currently widely used, as distinct from aviation.…”

The scope of the use of aluminum-alloy-based metal-matrix composite materials has been expanding in recent years. However, the high cost of raw materials is a considerable deterrent to the widespread implementation of products made of such composites. Therefore, the ranges of the said materials commercial application are yet inadequate to their technical and operational capabilities. So, methods of making metal-matrix composite materials directly from a liquid melt are currently of interest. This paper presents the theoretical studies and the results of practical experiments for the production of metal-matrix composite material by the internal oxidation method. There are described the results of mechanical tests and the microstructure of specimens confirming theoretical assumptions in the oxidation of aluminum melt array. A comparative analysis is given for the cost of producing an alloy containing 30% of Al2O3 particles obtained by adding the Al2O3 powder and an alloy obtained by the internal oxidation of the aluminum melt. The studied technology provides for the formation of aluminum oxide directly in the aluminum melt, thus enabling to produce a composite material by a single-stage process and ensuring the process efficiency.
