“…In particular, Mg matrix composites appear as possible substitutes for Al alloys [1][2][3][4]. Moreover, Mg matrix composites can present a better creep resistance than the unreinforced matrix alloy [4]. However, their production is faced with a number of challenges as well for the liquid routes as for the powder metallurgy route [2,3,5,6].…”

“…They have been recently reviewed by Avettand-Fenoël et al [10]. Particles or short fibres either have been deposited on the alloy surface [11] or have been placed in grooves [4,10,12] or in holes [13]. Alternatively, particles have also been loaded in holes drilled in the FSP tool [14,15].…”

In this work, friction stir processing (FSP) has been employed to fabricate metal matrix composites by incorporating B 4 C reinforcement particles into the aluminum AA6061 matrix. Taguchi experimental design, consisting of three factors and three levels, is used for minimizing the number of experiments. The factors considered are tool rotational speed, traverse feed and tool tilt angle. Desirability function analysis was employed to optimize the FSP parameters for simultaneous improvement of tensile strength and microhardness of the composites. The optimal parameters were found, and it was confirmed by experimental results. The composites fabricated using optimal process parameters exhibit a higher tensile strength (174 MPa) and microhardness (183 Hv). The tensile strength and microhardness values observed have been correlated with microstructural studies. Scanning electron micrograph revealed defect-free fabricated composites and uniform distribution of reinforcement particles in the stir zone.

“…Mishra et al [10] first reported the fabrication of composite by utilizing FSP. Since then, FSP has been applied extensively in fabricating of nanocomposite with various matrix alloys such as aluminum, [11][12][13] magnesium, [14,15] and titanium alloys, [16] although there are only a very few attempts on the production of graded structures via FSP. For instance, Hanagai et al [17] managed to produce functionally graded aluminum foams by changing the porosity percentage along the specimen's height.…”

In the present study, the functionally graded bulk Al-SiC nanocomposites were successfully fabricated by applying a novel multistep friction stir processing. Microstructural observations by scanning electron microscope indicated a proper distribution of SiC nanoparticles in the Al 6061 matrix. Microhardness profiles descended to 50 from 160 Hv due to the formation of compositionally gradient of SiC nanoparticles along the thickness. The tensile behavior of graded samples revealed a simultaneous enhancement of ultimate tensile strength (44 pct), strain at maximum stress (244 pct), and work of fracture (492 pct) with respect to the homogeneous sample. Furthermore, the graded samples sustained up to 4 pct strain after initiation of primary cracking, while the catastrophic fracture occurred instantly after cracking in the homogenous sample. A dimple-like ductile fracture surface was observed for the graded layers in which an increase in the SiC particle content will result in smaller dimple size.
