“…FSP in early stage were used for the improvement of micro structure but now a days fabrication of surface composite by using FSP is a very popular technique due to its numerous advantages [9][10] [11]. In FSP a profile tool pin after stir friction heat at the interface of tool and work insert by force in the work material and then follow the processing path as shown in the figure 1.…”

The magnesium is selected for the future implants material due to its excellent biocompatibility behavior. The biodegradable and biocompatible nature of Mg and its alloy make it prime choice for the development of bio-implants. The mechanical properties of Mg are similar to natural human bone therefore it can be used for temporary implantation for supporting a fracture bone. The rapid biodegradation of pure Mg before the healing time, raise the requirement to develop a metal matrix composites of Mg. The prominent technique of MMC fabrication is friction stir processing (FSP). The FSP is widely used for fabrication of surface composites and also used for grain structure refining and strengthening. The current article reviewed the various surface composites of Mg developed by FSP for alteration of biodegradation and mechanical properties. .

Mg–6xZn–xY (x = 0.8, 5, and 7 wt%) alloys containing an icosahedral quasicrystal phase (I‐phase) are synthesized, and the effects of Y doping on the microstructure and mechanical properties of the Mg matrix and I‐phase are investigated. The results show that as the Y content increases, the I‐phase content gradually increases, with the distribution of the I‐phase changing from a discontinuous to a continuous network and lamellar structures. Additionally, the eutectic structure (α‐Mg + I‐phase) in the alloys gradually increases, while the Mg matrix area decreases. The tensile strength of the as‐cast alloy initially increases and then decreases, reaching a maximum value at Y = 5. Heat treatment of the Mg–30Zn–5Y alloy reveals an optimal solid solution temperature of 320 °C, resulting in a tensile strength of 175.09 MPa and quasicleavage fracture characteristics. The maximum tensile strength of the alloy is achieved when the I‐phase distribution is continuous and the porosity of the Mg matrix is ≈66%. These results provide guidance for the microstructural design of I‐phase‐reinforced Mg alloys with rare earth elements to enhance their mechanical properties.
