Friction Stir Processing of Mild Steel/Al2O3 Nanocomposite: Modeling and Experimental Studies

Effect of friction stir processing on the tribological performance of Steel/Al2O3 nanocomposites

“…Nano-sized Al 2 O 3 powder with an average particle size of 70 nm was used as the reinforcement. We used the same FSP setup as in our previous researches [18]; in this setup, a shallow groove was machined through the center of the substrate surface with a width and depth of 1 and 2 mm, respectively. A technical hole was drilled at the beginning of the groove on the mild steel plate in order to ease the process and to decrease the tool wear in plunging phases.…”

“…As an example, Mishra et al [12] utilized FSP to embed second phase ceramic particles into the aluminum matrix to form surface composite layers (SCLs) with superior mechanical properties. Overall, FSP has turned into a versatile and successful technique for a wide range of purposes, including: (a) formation of ultrafine-grained structures in interstitial free steel (IF) steels [13], Al [14] and Mg alloys [15], (b) production of fine-grained microstructures with superplasticity characteristics [16], (c) homogenization of the microstructures of the nanocomposites [17], (d) refinement of microstructures [16], and (e) fabrication of SCLs [12,18].…”

“…Dispersion of hard ceramic nanoparticles in the matrix can enhance hardness [13,18], while good interfacial bonding and wettability preserves ductility. Altogether, FSP is proposed to produce improvement in tribological and wear properties of steels [19].…”
