“…More homogenous microstructure, strong interfacial bonding between the particles and matrix, as well as more stability of the composite are some of the advantages of in situ composites. [16][17][18][19][20][21] Ke et al 18 investigated the microstructure and mechanical properties of Al-Ni in situ composite produced by FSP using Ni powders. Their results showed that Al-Ni intermetallic compounds (IMCs), i.e.…”

“…Furthermore, microhardness and tensile strength of the composites were increased due to grain refinement and precipitation hardening. Azizieh et al 19 produced Al/Al 2 Cu in situ nanocomposite using FSP and Al-1100 and Cu nanopowders as the primary materials. Their results showed that Al 2 Cu particles were formed rapidly due to mechanically activated effect of FSP as well as high heat generation due to AlÀCu exothermic reaction.…”

Effects of Fe particle volume percent (from 0 to 5%) and changing the tool rotation direction in each pass were studied on the microstructure evolution and mechanical properties of the in situ Al/intermetallic composites produced by three passes friction stir processing (FSP) with ∼10 µm Fe particles. Optical and scanning electron microscopes were used for the investigation of the composite homogeneity, formation of Al–Fe intermetallic compounds, and fracture surfaces. Tensile and microhardness tests were also carried out to evaluate the mechanical properties of the composites. Solid-state reactions between the aluminum matrix and Fe particles led to in situ formation of Al3Fe and Al5Fe2 intermetallics in the composite. Changing the tool rotation direction in each pass reduced asymmetrical distribution of the reinforcing particles and resulted in better dispersion of Fe particles. Increase in the particle volume percent refined the composite average grain size from ∼35 μm in the sample processed without particles to ∼6 μm in the composite included 5 vol.% of the Fe particles. Zener limiting grain size relationship was used to estimate the volume fraction of the sub-micron particles in the composites. Enhancement of the reinforcing particle volume percent (to 5%) increased ultimate tensile strength and yield strength of the composite up to ∼60% and ∼95%, respectively, due to finer grain structure as well as the higher load-bearing capacity of the Fe and intermetallic reinforcing particles compared to the aluminum matrix. Contributions of the Hall–Petch effect and the other strengthening mechanisms in the yield strength of the composites were also investigated.

This review article investigates the mechanical and tribological properties of metal matrix composites (MMCs) prepared through friction stir processing technique. MMCs are developed materials with enhanced mechanical properties, exhibits their application in automotive and aerospace industries. The limitations of liquid metallurgical route can be reduced by using Friction Stir Processing (FSP) technique. FSP, a developed methodology technologically advanced by friction stir welding process is reviewed to fabricate the MMCs. In FSP, a hole or groove is made in the alloy. Reinforcement filled in the groove or hole are distributed in the matrix material by the FSP tool. Heat produced between the tool and the surface tends to the grain refinement. Owing to grain refinement, mechanical and wear properties of the composites are enhanced. In this review article, mechanical and wear behavior of the composite developed through FSP method are reviewed, which will help the researchers and industrial societies to fabricate the composite of required enhanced properties.

In the present scenario, composites are in huge demand in the industries due to their light weight, wear resistance, stiffness and high strength. The functional and structural properties were improved according to the need of industry. Particulate reinforcement is one of the methods to enhance the strength, ductility and toughness of the composites. Stir casting or friction stir processing technique was used to fabricate the metal matrix composite. For technology seekers it is very difficult to select appropriate techniques because there is lack of bench mark standards and industry experiences. The novel contribution of this paper is to provide systematic approaches and methodology which enable academic user as well as industry persons to select appropriate method and parameters for the fabrication of the metal matrix composite. This study guides the new researchers to fabricate and characterize the mechanical properties of aluminium-based composites reinforced with Al2O3, B4C, SiC, TiC, graphite and TiB2 particles.
