Aluminum Metal Matrix Composites

‘The micro/nano reinforced particle’ aluminum metal matrix composites (Al-MMCs) are widely used in manufacturing sector due to light-weight, superior strength-to-weight ratio, better fracture toughness, improved fatigue, and tensile property, enhanced corrosion resistance to harsh environment, etc. This article provides an overview of the manufacturing processes and different reinforcing elements used during the synthesis of Al-MMCs. Generally, the reinforced particles like carbides, nitrides, and compounds of oxides are used. Different organic, inorganic, industrial and agricultural waste which can be used for reinforcement in the aluminum matrix is highlighted with their feasible applications. The common mechanical properties (i.e. hardness, tensile and compressive strength, etc.) reported by different researchers are thoroughly discussed with the aim to highlight the amount of reinforcement and improvement occurred during processing. The formation and methodology for mixing condition and sintering behaviour of Al-MMCs are discussed to impart knowledge about the processing circumstances in powder metallurgical route. The affecting conditions during operating and responsible factor for the tribological behaviour are deliberated in a precise manner to recognize the potentiality of reinforcing particles in Al-MMCs. Finally, the different shortcomings and future prospects of the Al-MMCs are given to encourage the future research directions.

Aluminum Metal Matrix Composites

Metal Matrix Composites are developed in recent years as an alternative over conventional engineering materials due to their improved properties. Among all, Aluminium Matrix Composites (AMCs) are increasing their demand due to low density, high strength-to-weight ratio, high toughness, corrosion resistance, higher stiffness, improved wear resistance, increased creep resistance, low co-efficient of thermal expansion, improved high temperature properties. Major applications of these materials have been in aerospace, automobile, military. There are different processing techniques for the fabrication of AMCs. Powder metallurgy is a one of the most promising and versatile routes for fabrication of particle reinforced AMCs as compared to other manufacturing methods. This method ensures the good wettability between matrix and reinforcement, homogeneous microstructure of the fabricated MMC, and prevents the formation of any undesirable phases. This article addresses mainly on the effect of process parameters like sintering time, temperature and particle size on the microstructure of aluminum metal matrix composites.

Aluminum Metal Matrix Composites

Aluminum matrix composites reinforced by ceramic particles are well know for their good thermo-physical and mechanical properties. As a result, during the last years, there has been a considerable interest in using aluminum metal matrix composites (MMCs) in the automobile industry. These potential applications have greatly stimulated the tribological studies of MMCs under different operating conditions. In this paper, TiB – particles - reinforced aluminum - tungsten matrix composites were fabricated by the cost – effective squeeze – casting technology and their microstructure characteristics and mechanical properties were investigated. The microstructure observation showed that the produced composites were dense, with no micro-holes and obvious defects. Their wear resistance was evaluated using a pin on disc type equipment under dry wear conditions and found significantly increased compared to pure Al metal.

Aluminum Metal Matrix Composites

In the recent era, Metal Matrix Composites (MMCs) are one of the most vigorously studied topics in material science. Lightweight metals and its alloys create an intense attraction for tailoring new metal matrix composites to overcome conventional limitations like low strength. Aluminum metal matrix composites signify to the high-grade lightweight high-performance aluminum-based MMCs. The reinforcements in aluminum matrix composites could be in the form of particulates, whiskers, and continuous fiber or discontinuous fiber, where weight or volume fraction varies from a few percentages to 60%. Properties of aluminum metal matrix composites can be customized as per the demand of the industry by getting the appropriate combination of the metal matrix, reinforcements, and selective processing route. Nowadays many grads of aluminum matrix composites are fabricated by different routes where in situ route processing is more attractive compared with conventional ex-situ process because it delivers excellent wettability, thermally stability of reinforcements, the bonding strength between reinforcements and matrix, cohesive atomic structure, and fine grain size of reinforcements (specifically nano size). The devoted research work of aluminum matrix composites during the last three-decade generates a wealth of knowledge on the effect of reinforcements vis-à-vis mechanical, chemical, tribological properties of aluminum matrix composites. The acceptance of the aluminum matrix composites as engineering materials depends not only on the performance advantages of the composites, but it also depends upon the cheap, easy, and familiar fabrication technologies for these tailored materials.

Aluminum Metal Matrix Composites

In the present investigation, wear test is conducted on a pin-on-disc device at room temperature for both the age hardening and without age hardening conditions. Al7075 has been chosen as the matrix material. Hybrid aluminum metal matrix composites are produced utilizing stir casting route for enhancing the wear behavior and hardness number. The reinforcement used is silicon carbide with 5, 10, and 15 wt% and alumina as the reinforcement in 5, 10, and 15 wt%. In the aluminum matrix, microstructural characterization reveals homogeneous mixing of reinforcements. This investigation shows that the enhanced wear resistance is due to the increment weight fraction of reinforcement. By raising the sliding speeds, there is a reduction in the rate of wear and it reduces with increment in the sliding distance. With increasing weight fraction, there is decrement in the rate of wear of composites. In general, tribological property enhances because of the addition of the two reinforcements.
