Friction stir processing is a technique for the modification and fabrication of surface composites. Surface composites of aluminium have a diverse application in industries like aerospace and automobile. Here, B 4 C nano-particles (< 30 nm) have been employed as the reinforcement on AA7075 based substrate alloy and surface composites have been constructed at varying Tool rotation and Tool traverse speeds. The influence of these varying factors on the ultimate tensile strength (UTS), microhardness (Hv) and residual stress (RS) have been studied. Taguchi L9 orthogonal array was used for the DOE and the changes in the mechanical properties of these nine samples with regards to the tool rotation speeds of 800 rpm, 1000 rpm and 1200 rpm and the tool traverse speeds of 40 mm min −1 , 50 mm min −1 and 60 mm min −1 were investigated. It was found that between the two processing variables, Tool traverse speed was the more significant variable. 800 rpm and 60 mm min −1 were determined to be the optimum parameters for Friction stir processing and the predicted values of microhardness (Hv) through Taguchi analysis were the most accurate.

“…In the study by Zhang et al, (2018) the longitudinal residual stresses on the aluminum and copper side were tensile and compressive, as aluminum has an inferior Young's modulus as compared to copper. Butola et al, (2021) observed and compared the residual stress developed on the FSP tool pin during the fabrication process. It was found with more fabrication operation, the nature of stress changed.…”

Friction stir processing (FSP) of Al7075-T6 and Boron Carbide(𝐵4𝐶) nanoparticles as reinforcement were performed adopting Taguchi’s 𝐿9 orthogonal array. Optimisation of parameters which are transverse speed (TS), tool rotational speed (TRS), and tool pin profile (TP) based on residual stress and microhardness was done using Taguchi and Grey Relational Analysis (GRA). Result showed that minimum compressive residual stress and maximum microhardness were obtained at TS of 40 mm/min, TRS of 1200 rpm, and square tool pin profile. Analysis of variance showed that TP+TS with 49.63% contribution is the most significant factor to influence residual stress and microhardness.
