“…Ultimate tensile strength, hardness, and wear resistance increases as the reinforcement weight fraction increases. 13.The hardness of the AMMC decreases with the increase in the amount of tungsten carbide, zircon sand or both. The main interpretation made is that the hardness decreases with presence of these reinforcements in the metal matrix composite.…”

Among the various types of manufacturing process methods for discontinuous metal matrix composite, stir casting is the best suitable manufacturing process to fabricate particulate reinforced metal matrix composite. Its benefit is its simplicity, durability, and adaptability. The main issue in this process is proper wetting of reinforcement in aluminium matrix material. Only proper wetting results in a homogeneous dispersion of reinforcement material, and these homogeneous dispersions help to improve the properties of metal matrix composite material. The purpose of this paper was to discuss the outline of the stir casting process, process parameters, and the contribution effect of process parameters. This paper also presents about of the conditions should follow during the addition of reinforcement material and matrix material pouring in mould cavity. This paper also discusses the conditions that must be met during the addition of reinforcement material and matrix material pouring in the mould cavity. This paper also looked into the impact and contribution of stirring casting time, speed, and temperature in aluminium metal matrix composites, as well as processing issues in aluminium metal matrix composites, challenges, and research opportunities.

“…In this research work, a commercial grade aluminium alloy Al 7075 was used as the matrix material, with the reinforcement of Nano graphene , B 4 C and Inconel alloy. The hybrid composites were fabricated with reinforcement of ( 0.5,1,1.5,2) Nano graphene, B 4 C (2,4,6,8), Inconel alloy 625 (2,4,6,8) Wt.%. The chemical composition of Al 7075 analysed and shown in Table 1.…”

“…Reda et al [6] and Clark et al [7], in their studies on Al 7075 reported, that pre-aging at various retrogation temperatures improves the hardness, tensile properties and electrical resistivity. Kim et al [8] ended that the hardness of aged Al 7075 alloy rises. Doel and Bowen [9] reported the enhanced tensile strength and lesser ductility of the Al 7075 reinforced with 5 and 13 lm SiC particles, than that of unreinforced material.…”

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.

Teknolojinin hızla gelişmesi ile birlikte, imalat, havacılık ve otomotiv sektörlerinde yaygın olarak kullanılan standart malzemeler yerini yeni nesil yüksek mukavemete ve hafifliğe sahip malzemelere bırakmaktadır. Özellikle, Tungsten karbür (WC) ve Grafenin sahip olduğu yüksek termal ve elektriksel özellikler, yüksek elastisite modülü, yüksek mukavemet gibi üstün özellikleri sayesinde alüminyum matrisli kompozit malzeme üretiminde büyük etki ve avantajlara sahiptir. Bu çalışmada, WC ve Grafen takviyelerinin alüminyum matrisli kompozit malzemelerin mekanik özelliklerine etkisi ile ilgili çalışmalar incelenerek sunulmuştur. Alüminyum matrisli kompozitlerin mekanik özelliklerinin iyileştirilmesinde %20'ye kadar WC ve %0.7'ye kadar grafen katkısının etkili olduğu raporlanmıştır. Grafen ilavesinin %0.5'ten fazla arttırılması topaklanmalara, WC ilavesinin %30'dan fazla arttırılması ise gözenekliğin artmasına ve mekanik özelliklerin azalmasına neden olmaktadır.
