“…Also, the variations of the preferred orientation are significant near the centreline which experienced severe plastic deformation (Woo et al, 2006). On the other hand, Particles can have marked effects on the restoration kinetics, microstructure, texture of the SZ (Cao et al, 2013;Shafiei-Zarghani et al, 2016), and its properties (Shafiei-Zarghani et al, 2015). Basically, the study of microstructural evolution and texture development in the centre of SZ (especially in the presence of particles) can improve the essential understanding of materials response to FSP.…”

The application of ball-milling for reactant powders (Fe O +Al) to form in situ nanosized reaction products in the stir zone of 1050 aluminium alloy was examined and the evolution of microstructure, grain boundaries and microtexture of the fabricated Al/(Al Fe +Al O ) nanocomposite was investigated. The mean matrix grain size of the fabricated nanocomposites by the combination of ball milling and friction stir processing were found to be ∼3.2, 3.1 and 2.1 μm for 1, 2 and 3 h milled powder mixtures, respectively. The fraction of high-angle grain boundaries increased markedly in the stir zone indicating the occurrence of dynamic restoration of the aluminium matrix. This was also associated with increasing of the fraction of low ∑CSL boundaries. In addition, the fraction of high-angle grain boundaries increased as the reaction product increased. The developed textures were compared with the most important deformation and recrystallisation texture components of cubic close packed structure. Some of the main texture components formed due to the restoration of aluminium in the stir zone of the material with no powder addition were Cube {001}<310>, BR {236}<385> and R (or retained S{123} <634>); these are usually found in the rolled materials. However, the presence of nanosized reaction products in the fabricated nanocomposite changed the texture components to the dominant Goss {011}<100>, P {011}<122> and R{124}<211> textures.

“…However, their wider applications in many engineering industries are rather limited, which is mainly because under severe working conditions, their mechanical properties such as strength and hardness become poor. In order to improve the mechanical properties of Ti matrix composites, some hard particles, including TiC, TiB, TiN, SiC, ZrO 2 , Al 2 O 3 and Y 2 O 3 et al, were often introduced into Ti matrix composites using various fabrication technologies [15][16][17][18][19][20][21][22]. Multi-wall CNTs were also used to reinforce Ti matrix composites, and the yield strength and ultimate tensile strength of Ti matrix composites with these CNTs were improved by 40.4% and 11.4%, respectively, [23].…”

“…Because of the isotropy, compatibility with hot processing, low cost, and the controllability of properties of the discontinuous TMCs, it has attracted wide attention from researchers all over the world. Up to now, various reinforcements have been used to improve the properties of TMCs, such as Al 2 O 3 [1], SiC [2], graphene [3][4][5], CNTs [6], TiC [7], TiB [8][9][10][11], Nb 2 O 3 [12], La 2 O 3 [13] and so on. Among all the reinforcements mentioned in literature, graphene, TiC and TiB were most widely investigated.…”

In this study, three titanium matrix composites (TMCs) reinforced with graphite, graphene, and boron carbide (B4C) were fabricated through powder metallurgical techniques. The morphologies of grains and secondary phases of these TMCs were observed through Optical Micrograph (OM) and Scanning Electron Microscopy (SEM). The results of the mechanical properties of the TMCs showed that B4C was the most effective in increasing the strength and hardness, while the strengthening effect was comparable between graphite and graphene. The plasticity of the graphene reinforced TMC decreased sharply because of the formation of strip-like agglomerations. The small sizes, large volume fraction, and uniform distribution of the secondary phases contributed to the enhancement of strength and hardness in boron carbide reinforced TMC. Although the thermal properties of the TMCs were lower than pure titanium in the temperature range of 25~300℃ , the thermal conductivities of the TMCs were all above 15.6W/m· K.
