Carbon nanotubes are the latest trends in the study of powder metallurgy and nanocomposites. This is due to the exceptional properties like superior mechanical and electrical properties, high Young’s modulus, high tensile strength, smaller diameters, high elongation and high chemical stability. CNT’s is an attractive reinforcement for metal matrix composites. CNT are now reinforced with many metal matrix composites like aluminium, iron, manganese, copper etc. with considerable change in density of the material. Due to high aspect ratio that facilitates their tubular structure and high strength the CNT’s are reinforced with ferrous powder by implying powder metallurgy process and the results have been recorded. Such recordings of the effects of CNT on Ferrous powders are reviewed in this paper.

Metal matrix composites (MMCs) are the new generation materials that combine both the metallic properties (ductility and toughness) and ceramic characteristics (high strength and modulus), leading to higher strength in shear and compression, at higher service temperatures. Titanium matrix composites possess light weight, high strength and good corrosion resistance and are used as structural materials in automobiles and aerospace industries. In the present study, in situ Ti-TiB composites were fabricated by reinforcing (2, 5, 10 and 20 wt. %) TiB2 powder (mean size <10 microns) into titanium powder (mean particle size ~26.58 μm) and subsequently consolidated by vacuum sintering at 1300 °C for 3 h. X-ray diffraction, scanning electron microscopy (SEM) and density measurements were carried out to characterize the prepared composites. The results showed that all compositions led to high density composites, and the hardness of the composites increased with an increase in the amount of reinforcement. The mechanism of vacuum sintering is yet to be understood in the consolidation of composites and the detailed evolution of microstructure needs to be analysed.

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.

Abstract This paper interprets the effect of sintering parameters like sintering time and sintering temperature as well as various sintering methods on distinct properties of the material. The variation of Physical, mechanical, and Tribological behaviour depending on sintering temperature, time and method based on various aluminium metal matrix composites have been investigated. The advantages of aluminium metal matrix composites are high strength to weight ratio, high wear resistance, and erosion resistance, etc. Aluminium Metal matrix composites have vast applications in various fields like structural, automobile, and aviation industries. The optimum value of sintering parameters and choice of sintering methods has a major role in getting these required properties of aluminium metal matrix composites prepared by the powder metallurgy process.
