“…This has made AZ91 a popular light metal alloy especially among automotive industries whose aim is manufacturing lightweight vehicles (Srinivasan et al 2010). However, the use of AZ91 in different industries is not yet extended comparing to its competitors such as aluminum alloys and plastics, partially due to the difficulty in controlling its microstructure (Asadi et al 2010a).…”

Background: Recently, some researchers have simulated FSW using FEM and studied the influence of process parameters and tool geometry on material flow, welding force, and temperature and strain distributions during friction stir processing. Additionally, in terms of microstructure modeling, various approaches such as the Cellular Automaton (CA) model have been developed to simulate microstructural evolution during plastic deformation processes. Method: In this work, a finite element model (FEM) is established to study the microstructure evolution during friction stir welding (FSW) of AZ91 magnesium alloy. To this aim, first, the hot compression tests at different temperatures and strain rates were carried out to achieve the flow stress curves. Then, the hardening parameter, the recovery parameter and the strain rate sensitivity were calculated according to flow stress results and using the Kocks−Mecking model. Next, a continuum based thermo-mechanically coupled rigid-viscoplastic FEM model was proposed in Deform-3D software to simulate the FSW of AZ91 magnesium alloy. To evaluate microstructure of the weld zone a model is proposed based on the combination of Cellular Automaton and Laasraoui-Jonas models.

“…Developing new strategies to increase the level of incorporation, distribution of secondary phase, and increasing the thickness of the affected surface layer is in a great need to utilize the high potential of FSP technique in producing surface composites. For example, Asadi et al (2010) studied the effect of penetration depth (PD) of FSP tool and demonstrated that the PD also has a great influence on composite formation. Further, the authors have shown the effect of (PD) on composite formation again depends on tool travel and rotational speeds.…”

Friction stir processing (FSP) is a solid-state processing method, which recently gained wide popularity to modify the microstructure of metallic surfaces and to produce surface composites. For the past decade, composites of different materials such as aluminum, copper, magnesium, titanium, and their alloys were successfully produced by FSP. The amount of secondary phase that is dispersed at the surface of the workpiece during FSP and the level of dispersion depend on many factors such as tool design, processing parameters, and type of material. Recently, the method of secondary phase incorporation into the surface metals was also considered as an important factor in developing surface composites by FSP. A few strategies such as groove filling, holes filling, sandwich method, direct method, and surface coating followed by FSP methods have been developed as promising ways of secondary phase incorporation into the surface of the materials during FSP. The aim of this review paper is to give a comprehensive summary of different methods developed to disperse the secondary phase into the surface of the workpiece during FSP to produce surface composites. The strategies have been explained, compared, and discussed to suggest an appropriate method based on the requirement to adopt in developing surface composites.

“…Devinder Yadav et al [15] [21] were added nanosized SiC and Al 2 O 3 particles to as-cast AZ91 alloy, and a surface layer with very fine grain structure was produced via friction stir processing (FSP).They found the effects of reinforcing particle types and FSP pass number on the microstructure, microhardness, and on tensile and wear properties of the developed surfaces.A.Devaraju et al [22] studied Influence of reinforcements (SiC and Al 2 O 3 ) and rotational speed on wear and mechanical properties of aluminum alloy 6061-T6 based surface hybrid composites produced via friction stir processing. Parviz Asadi et al [23] Produced AZ91/SiC composite by friction stir processing (FSP). They found that by using 5 μm SiC particles in AZ91, the stir zone grain size reduces and stir zone hardness increases.…”

-Composites manufacturing is one of advance manufacturing technique in the history of materials. Metal matrix composites (MMCs) have high mechanical properties and modified microstructures. Friction Stir Process is a modified technique to produce MMCs. In this Review Paper, I discussed a number of research papers and work done by different authors. Mainly in these papers, I discussed materials, Process Parameters and responses used. Cu(copper) and Al(Aluminium) matrix is used in many research papers. Aluminium and Silicon reinforcing particals are used. These particles change the property of material. These particle should be properly mixed with matrix for producing good results.
