Friction stir processing (FSP) becomes remarkable technique to create metal matrix composites (MMCs). FSP can be used to produce MMCs of different materials like aluminium, copper, magnesium, steel etc. Due the excellent mechanical properties like higher strength to weight ratio, higher corrosion resistance and lighter weight density brand aluminium as a material of choice for different structural application in different industries like defense, marine, automobile and aircraft. Many researchers have found that the microstructure as well as mechanical properties of aluminium can be altered through reinforcing particles like SiC, TiC, Al2O3 etc. Microstructure, mechanical and wear properties of aluminium base material can also altered by modifying different variables involved in FSP. This paper is a state of art of review of consequences of different variables of FSP on mechanical properties of aluminium metal matrix composites (AMMCs) fabricated through FSP method.This review article will also provide the future research direction for aluminium as a base metal.

“…The third approach involves FSP admixing the powder particles into the base metal in order to form composite structures [ 25 , 26 ]. To enable such a process, the powder must be first delivered to the base metal workpiece using any suitable technique such as, for example, loading the powder either into cut grooves [ 25 ] or into a series of drilled holes [ 25 , 27 ]. The variable width groove technique may also be applied for obtaining gradient and shaped structures [ 28 ].…”

This paper is devoted to using multi-pass friction stir processing (FSP) for admixing 1.5 to 30 vol.% copper powders into an AA5056 matrix for the in situ fabrication of a composite alloy reinforced by Al-Cu intermetallic compounds (IMC). Macrostructurally inhomogeneous stir zones have been obtained after the first FSP passes, the homogeneity of which was improved with the following FSP passes. As a result of stirring the plasticized AA5056, the initial copper particle agglomerates were compacted into large copper particles, which were then simultaneously saturated by aluminum. Microstructural investigations showed that various phases such as α-Al(Cu), α-Cu(Al) solid solutions, Cu3Al and CuAl IMCs, as well as both S and S’-Al2CuMg precipitates have been detected in the AA5056/Cu stir zone, depending upon the concentration of copper and the number of FSP passes. The number of IMCs increased with the number of FSP passes, enhancing microhardness by 50–55%. The effect of multipass FSP on tensile strength, yield stress and strain-to-fracture was analyzed.

In this work, friction stir processing (FSP) was used to successfully embed boron carbide (B4C) particles into an aluminum matrix (AA6061-T6). Four specimens of aluminum 6061 composite reinforced with 4%, 6%, 8%, and 10% volume fraction of B4C were manufactured. The effects of B4C particles volume fraction on microstructure, mechanical and wear properties are investigated. The microstructural investigations demonstrated that a rise in the volume % of reinforcement greatly decreased the matrix grain size. The manufactured AA6061-T6 loaded with B4C surface composites demonstrated homogeneous B4C particle dispersion, with no significant particle clustering in the stir zone. In addition, it was established that increasing the volume fraction of B4C particles promoted grain refinement, increased hardness, and tensile strength. X-ray diffraction (XRD) was used to identify the reinforcement dispersion. For AA6061-T6 with 10% B4C particles, a maximum hardness value of 163 HV was obtained in the stir zone. Maximum yield strength of 165 MPa and ultimate tensile strength of 220 MPa were attained by AA6061-T6 with 10% B4C particles, which is an improvement of 21% over the specimen FSP without reinforcement. The strengthening of the grain refining was attributed for the increase in hardness and strength. The ductility was reduced by the incorporation of more B4C particles. Comparing the surface composite loaded with B4C to unreinforced friction stir processing and AA6061-T6 as received, it demonstrated superior wear resistance.
