“…A homogenous distribution of the (Al 2 O 3 -ZrO 2 ) reinforcements in the Al matrix was obtained. Characterization of the mechanically milled powders confirmed uniform distribution of the reinforcement phase [5]. Ramesh.B.T discussed about the carbon nano tubes reinforced aluminum matrix composite which had been successfully developed through powder metallurgy technique and it is well preferred for fabrication of nanocomposite materials [6].…”

Aluminium metal matrix composites (AMMCs) are being considered as a group of superior material for its lightness, strength, high specific modulus, low coefficient of thermal expansion and good wear resistance properties. Solid state and liquid state processing methods are used to fabricate AMMCs. Achieving a uniform distribution of reinforcement within the matrix is one such challenge, which affects directly on the properties and quality of composite material. Powder metallurgy route, one of the solid state processing methods can be effectively used to get uniform dispersion of reinforcements with aluminium metal matrix. This paper presents the summary of the ball milling and stir casting processes to fabricate the AMMCs and its applications. Major issues like ball milling time, dispersion of reinforcements, grain size, the stirring time and speed are discussed. Also the effect of different reinforcement for AMMCs on the mechanical properties is discussed in detail.

Recently, the increasing need for good quality, high performance, and low-cost materials has directed research towards composite materials rather than monolithic materials. In the case of metal matrix composites (MMCs), composites based on aluminum matrix have been widely developed for the automobile and aerospace industry as well as structural applications due to having a low cost, high wear resistance, and high strength to weight ratio.Moreover, a facile and economical method for the production of the composites is a very important factor for expanding their application. Ceramic reinforcements such as graphite, silicon carbide, alumina, and fly ash particulates can be introduced in metal matrices. Moreover, there has been considerable interest in developing Al-Li alloys and composites because of having high specific strength and high specific modulus. The present article has focused on the development of aluminum-lithium alloy composites as well as their production methods.

“…AlSiCNT composite powder preparation [3] for CNT 5% and 10% by weight by ball milling preparation was the first task and takes maximum time before coating. The ball mill container was filled with 25% of its total volume with aluminum powder of 325 mesh size (45µm) and silicon powder of 325 mesh sizes (45µm), which are weighed 72gm and 23gm respectively.…”

Recent trends shows powder metallurgy composites are most familiar due to its wide applications in the areas like defense, aircraft, automobile, sports etc. Powder metal mixtures are prepared for surface coating in the areas where high corrosive and heat resistance are required. Carbon Nanotubes are widely used in the field of engineering with its remarkable mechanical, electrical properties and very good reinforcement in composite preparation. In this research, multi wall Carbon Nanotube along with Aluminum and Silicon powder were mixed thoroughly by ball milling process. The powder mixture (AlSiCNT) reveals that Carbon Nanotube are well dispersed uniformly with Aluminum and Silicon which promotes toughening mechanism with good reinforcement. The AlSiCNT mixture is then coated over the surface of Aluminum alloy 6061 and Stainless steel 304 L by plasma spraying technique. Tensile test, micro hardness tests with micro structural study were carried out over the composite. Coated composite reveal better mechanical properties than the base metals.
