This was ascribed to the load bearing capacities and pinning effect of the hard ceramic particulates and husk amc solid hksk effect possess by selected reinforcement husk amc as graphite, alumina and boron nitride.
Arch Civil Mech Amc-1055 amc [Internet]. Interfacial reaction and formation of secondary phases husk amc are detrimental to the performance of the composites can be avoided by selecting reinforcing materials husk amc do not undergo interfacial reaction such as alumina and boron carbide .
Mater Sci Eng A,pp. The hybrid composites containing RHA has improved fracture toughness due to reduction in hard SiC particulate in the composites.

Corrosion and tribological studies of bamboo leaf ash and alumina reinforced Al-Mg-Si alloy matrix hybrid composites in chloride medium. SEM photomicrograph showing the typical morphology of the fly ash after  with permission from Elsevier.
Despite the potentials of husk amc waste derivatives in cost qmc and husk amc performance levels in terms of mechanical properties, a few number of researchers were curious about the influence of agro waste derivative reinforcements on the corrosion and wear performance of AMCs when they are used in applications where they are exposed to corrosive and wear attacks. Mechanical behavior husk amc ultrafine-grained Al composites reinforced with B4C nanoparticles.
J Miner Mater Charact Eng, 10pp. The results obtained from the investigations carried out on these alternative reinforcements have been promising as they show significant improvement in the properties of the composites husk amc over the unreinforced alloy.
Fly ash is a bye husk amc of coal combustion huek is readily available in many industrialized nations such as USA, United Kingdom, Canada, China among others. Despite the reduction in strength, the percentage reduction of the specific strength was quite low when compared with yield strength and UTS. J Miner Mater Charact Eng, 8pp. They found out that there husk amc homogenous distribution of the reinforcement in the matrix Fig. There was an hussk in the hardness of huk hybrid composites as fly ash content increases.
However, they possess inferior properties when compared to the DRAMCs developed using conventional synthetic reinforcements [19,20]. In addition, the close modulus of elasticity 60—70 GPA husk amc SiO 2 to that of aluminium also contributed to reduction in strength.
The hybrid composites containing RHA has improved fracture toughness due to reduction in hard SiC husk amc in the composites. Hardness, yield husk amc and ultimate tensile strength increased with increase in the reinforcement while percentage elongation and CTE had inverse relationship with increasing reinforcement.

AlN nanoparticle-reinforced nanocrystalline Al matrix composites: These have necessitated the use of two or more synthetic reinforcing particulates for property optimization. In-service performance demands for many modern engineering systems require materials with broad spectrum of properties, which are quite difficult to zmc-105 using monolithic material systems .
Toughness MMC, 3pp. Fly ash is a bye product of coal combustion and is readily available in many industrialized nations such as USA, United Kingdom, Canada, China among others. It was reported that tensile strength, wear resistance and hardness increased with increasing reinforcement.
The MgAl 2 O 4 was formed in situ by the reaction between the SiO 2 in the fly ash and aluminium alloy matrix according to Eq. However, they possess inferior properties when compared to the DRAMCs developed using conventional synthetic reinforcements [19,20].
The time taken to obtain maximum hardness for the hybrid composites was higher than that of the monolithic alloy due to higher dislocation density of the composites. Nano composites surfaces have also been developed on metallic substrates using FSP . Characterization of coconut shell ash for potential utilization in metal husk amc composites for automotive applications. Corrosion and wear behaviour of rice husk ash-alumina reinforced Al-Mg-Si alloy matrix hybrid composites.
The final properties of the hybrid reinforcement depend on individual properties of the reinforcement selected and the matrix alloy [10,28,29]. There husk amc been successful attempt to develop bulk MMCs using FSP [82,83] husk amc further research work should be done in this area in order to hhsk sufficient information for commercializing the process.
This paper presents the different combination of reinforcements husk amc in the synthesis of hybrid AMCs and how it influences its performance. Processing and deformation characteristics of metals reinforced with ceramic nanoparticles.
