“…In common practice, a groove [18][19][20][21] or a series of holes [22][23][24][25] is created on the top surface of the plate and is filled with reinforcement powder [18,19,22,24] or slurry of powder in a volatile medium [20,21,23,25]. Groove or holes can be made under the pin, either in advancing side or in retreating side under the shoulder.…”

Aluminum matrix composites are widely used in aerospace, automotive industry and defense sector owing to its excellent weight-to-strength ratio. Friction stir processing has emerged as an excellent technique to produce particle reinforced as well as fiber reinforced aluminum matrix composites. This article is a state of the art of aluminum matrix composite fabrication by friction stir processing route. The fabrication procedure has been discussed with carefully mentioning the parameters associated with the process. Microstructures and consequent mechanical properties of the composites have been evaluated. Particular attention is given on the microstructural modification and strengthening mechanism. Also the wear and corrosion behavior of the composites has been discussed thoroughly. Finally, the article has been concluded with some suggestions toward future work.

“…In case of both groove filling and hole filling methods, certain care is taken to avoid splashing out of powder. Usually, a pinless tool, i.e., a tool made of only shoulder, is used to close the groove [18,19,27]. After filling in the hole, the powder is compacted by means of pressure [24,28].…”

In many applications, surface properties of materials or components are more important than the entire volume material properties. The hardness, wear and corrosion resistance of material mainly depends on the surface properties. Improved surface properties also increased the life span of components. The friction stir process is a novel solid-state processing technique that is widely used for welding difficult-to-weld materials. In this paper, the applications of the friction stir process in surface modifications and fabrication of aluminum matrix surface composites were discussed. The effects of friction stir process parameters, tool design, reinforcement and reinforcement techniques on the surface properties were also reported.

“…Aluminum alloys are important for many applications such as aerospace and automotive industries etc…., because of their light weight and high strength to weight ratio [1]. Because of the good properties of aluminum alloy 6061-T6, light weight, good strength, good erosion and corrosion properties, it is widely used in marine areas, cars and aircraft [2]. Homogenising and refining the grain structure of the alloy get better mechanical properties.…”

This work is devoted toward optimization of the parameters of the friction stir processing (FSP) which effect on tensile strength of aluminium alloy AA6061-T6 of 6mm thick plate by applying a certain number of tests utilizing the Taguchi method. Design of experiment (DOE) has been applied for the determination of the most important parameters influencing ultimate tensile strength. FSP was achieved under three different rotation speeds (800,1000 and 1250) rpm, different transverse speeds (16,25 and 32) mm\min, and number passes(1,2 and 3) in the same direction and tool tilt angle was 2° with using threaded cylindrical pin profile. The best FSP parameters were 1250 rpm and 32 mm\min and two passes. It was found that the higher hardness value was 75HV in stir zone center and then decreases toward the TMAZ, HAZ and the base metal
