“…It can be used to build nano-composite layer/surface composite as well as bulk composites of limited thickness/dimensions. It often leads to uniform distribution of reinforcement and refined grain size [65][66][67][68][69][70]. The FSP process uses a shouldered rotating tool that pass over the matrix containing nano-ceramic particles.…”

Magnesium based nanocomposites are new lightweight and high-performance materials for potential applications in automotive, aerospace, space, electronics, sports and biomedical sectors primarily due to their lower density when compared to aluminum-based materials and steels. Synthesis of magnesiumbased materials is relatively challenging and accordingly this chapter explicitly provides an insight into various techniques hitherto devised/adopted by various researcher for synthesizing magnesium based nano-composites (MMNCs). Overall processing of MMNCs often includes combination of primary and secondary processing. Primary processing fundamentally leads to the initial formulation and creation of MMNC ingots by solid, semi-solid or liquid state processing routes. This is followed by secondary processing that includes plastic deformation or severe plastic deformation to alleviate inhomogeneity, clustering of particles and fabrication defects to enhance the properties of the MMNCs. This chapter provides an insight into different fabrication methodologies, their benefits and limitations for MMNCs.

“…So far, a lot of reinforced particles, such as TiC ( Balakrishnan et al, 2015 ; Navazani and Dehghani, 2015 ), TiAlC ( Gobara et al, 2015 ), Al 2 O 3 ( Azizieh et al, 2018 ), B 4 C ( Vedabouriswaran and Aravindan, 2018 ), MWCNT ( Morisada et al, 2006b ; Arab et al, 2017 ), and SiC ( Morisada et al, 2006a ) have been added in Mg matrix by FSP, improving the mechanical properties of the alloys. For example, Navazani and Dehghani (2015) and Balakrishnan et al (2015) studied the microstructure and mechanical properties of AZ31/TiC composites fabricated by FSP.…”

“…The results showed that TiC particles distributed uniformly in AZ31 Mg matrix after FSP, which promoted the grain refinement and improved the microhardness. According to the research of Azizieh et al (2018) , adding Al 2 O 3 to AZ31 Mg alloy with FSP effectively increased the wear resistance of the material. It has been reported ( Vedabouriswaran and Aravindan, 2018 ) that after adding B 4 C particles to RZ 5 Mg alloy, the coarse grains in base metal (BM) become the fine grains in composites due to the pinning effect of reinforced particles.…”

Magnesium (Mg) and its alloys have attached more and more attention because of their potential as a new type of biodegradable metal materials. In this work, AZ31/ZrO2 nanocomposites with good uniformity were prepared successfully by friction stir processing (FSP). The scanning electron microscope (SEM) and transmission electron microscope (TEM) were used to characterize the microstructure of the composites. The mechanical properties, electrochemical corrosion properties and biological properties were evaluated. In addition, the effect of reinforced particles (ZrO2) on the microstructure and properties of the composite was studied comparing with FSP AZ31 Mg alloy. The results show that compared with the base metal (BM), the AZ31/ZrO2 composite material achieves homogenization, densification, and grain refinement after FSP. The combination of dynamic recrystallization and ZrO2 particles leads to grain refinement of Mg alloy, and the average grain size of AZ31/ZrO2 composites is 3.2 μm. After FSP, the c-axis of grain is deflected under the compression stress of shoulder and the shear stress of pin. The ultimate tensile strength (UTS) and yield strength (YS) of BM were 283 and 137 MPa, respectively, the UTS and YS of AZ31/ZrO2 composites were 427 and 217 MPa, respectively. The grain refinement and Orowan strengthening are the major strengthening mechanisms. Moreover, the corrosion resistance in simulated body fluid of Mg alloy is improved by grain refinement and the barrier effect of ZrO2.

“…Several techniques were adopted to produce magnesium based surface metal matrix composites (SMMCs) [3][4][5]. Friction stir processing (FSP) is one of such successful methods used for the development of surface composites [6][7][8][9][10][11][12]. FSP is a severe plastic deformation technique that allows the processing of materials within the solid state itself.…”

In the present study, the surface of AZ91 Mg alloy was modified by incorporating boron carbide (B 4 C) particles using friction stir processing (FSP). Sliding wear behavior of these developed AZ91/B 4 C surface composites was investigated against AISI 52100 steel ball using linear reciprocating tribometer. Hardness tests reveal that the hardness of the fabricated surface composite (∼137.47 HV) is significantly increased compared to the base metal (∼95.5 HV) due to the presence of B 4 C particles.Wear tests were conducted on the samples at two different sliding velocities; 0.06 m s −1 and 0.12 m s −1 . It was observed that at higher sliding velocity of 0.12 m s −1 , AZ91/B 4 C surface composite exhibited lower friction coefficient value in comparison to that of the base metal, whereas it is vice versa at the low sliding velocity of 0.06 m s −1 . However, surface composites exhibited superior wear resistance at both the sliding velocities, in comparison to that of the base metal. Scanning electron microscopy and energy-dispersive spectroscopy analysis of the wear tracks were carried out to understand the wear mechanisms. From the observations, a combination of abrasive, adhesive, and oxidative wear mechanisms were found to be prominent.
