“…32,33 Additionally, the thickness of the workpiece is not reduced in FSP, making the superplastic forming of thick plates feasible. 34,35 Selective superplastic forming of plates by FSP has been successfully demonstrated. 36 The primary purpose of FSP, in the beginning, was to make the grain size very fine to obtain homogeneity in the microstructure in addition to enhancing the mechanical traits of Al-based alloys; however, in recent times, FSP has proved to be a process with great promise in manufacturing of MMCs.…”

There is a dynamic shift underway from traditional technology due to the revolution of industries. Conventional techniques are hindered and advanced technologies are coming into existence. Friction stir processing is one of the processes spreading its usage across the field. Formation of surface composites with inclusion ceramics is one of the greatest advantage investigated in this study. Metal matrixes are far better than alloys as properties which are desired could be easily achieved with varying composition. Aluminium-based composites possess higher strength to weight proportion which is highly recommended in the field of aerospace and automobile industry mainly due to its lower density. This study deals with various process parameters that researchers have come across till date related to FSP. Furthermore, research based on friction stir processing of aluminium reinforced with ceramics are discussed mainly based on SiC or B4C. This comprehensive review tries to fill the gaps in developing a deep understanding of aluminium-based composites when friction stir processed ceramics improves mechanical as well as wear properties of material to a larger and extent and can easily replace conventional materials leading to cost effective as well as free from defects.

“…squeeze casting or stir casting, are faced with important issues related to the matrix/reinforcement interface. On one hand, for C fibre MgMCs, the poor wettability between carbon and pure Mg [4][5][6] may result in inadequate distribution of the reinforcing phase in the metallic matrix [2,7]. On the other hand, excessive interfacial reactions between the reinforcement and the molten metal may prove detrimental to the integrity and mechanical behaviour of the composite.…”

“…In this work, we investigate the deformation under tension and compression and the damage behaviour of short fibre-reinforced composites produced by FSP through a combination of experiments and micromechanical modelling. The AZ91D (Mg-Al-Zn) alloy is used as matrix material, and the FSP processing route follows previous work [5,17]. Our technology presents significant advantages in terms of ease of implementation and scalability.…”

Friction Stir Processing (FSP) is an attractive manufacturing technique to produce Mg matrix composites since it avoids the problem of excessive reactivity between reinforcement and matrix encountered in liquid-phase processing routes. However, the strength of the interface in C-reinforced Mg matrix composites produced by FSP remains to be assessed. A short fibre composite has been fabricated by FSP a stack of a C-fabric between two Mg-AZ91D alloy sheets. In order to elucidate the interplay between matrix hardness and interface bonding strength, the work investigates the influence of heat treatment on the mechanical properties of the composites. An incremental Mori-Tanaka model is developed to analyse the relative roles of heat treatment and C-fibre reinforcement on the flow strength and ductility of the composites in tension and compression. The mean-field model provides an estimate of the stress at the matrix/fibre interface, from which a simple debonding criterion can be derived. Comparison between model predictions and experimental data indicates that damage in the FSP composites is triggered by early interfacial debonding. Based on Finite Element simulations of a tensile test carried out in-situ in a scanning electron microscope, the critical interfacial stress for debonding was identified to be 435 MPa in simple traction but only 250 MPa when damage is governed by shear. This explains the limited strengthening by C fibres observed in heat treated composites.

“…5 Liquid-solid extrusion process following vacuum infiltration (LSEVI) technique was a new technique for fabrication of metal matrix composites, which integrated preform heating, magnesium alloy melting, vacuum pouring and pressure infiltration in a whole system and significantly improved the material utilisation. [13][14][15][16] However, the fabrication of large scale and thin wall C f /Mg components bring great challenge to the uniform infiltration along both vertical and horizontal direction, and the key is the reasonable selection of fabrication parameters.…”

Carbon fibre reinforced magnesium matrix (C f /Mg) composite components were made by liquidsolid extrusion process following vacuum infiltration technique. The effect of varying fabrication parameters (extrusion temperature, infiltration pressure and filling pressure) on the forming quality of C f /Mg components was investigated. The experimental results showed that the extrusion temperature and the infiltration pressure played important roles, and the filling pressure played a secondary role. The components can be obtained at an extrusion temperature of 5908C, an infiltration pressure of 20 MPa and a filling pressure of 0.2 MPa. The ultimate tensile strength of the C f /Mg composite components was 290 MPa, which was increased by 81% compared with that of casting AZ91D.
