Surface development by reinforcing nano-composites during friction stir processing – a review

Abstract

Purpose Friction stir processing (FSP) is overviewed with the process variables, along with the thermal aspect of different metals. Design/methodology/approach With its inbuilt advantages, FSP is used to reduce the failure in the structural integrity of the body panels of automobiles, airplanes and lashing rails. FSP has excellent process ability and surface treatability with good corrosion resistance and high strength at elevated temperatures. Process parameters such as rotation speed of the tool, traverse speed, tool tilt angle, groove design, volume fraction and increase in number of tool passes should be considered for generating a processed and defect-free surface of the workpiece. Findings FSP process is used for modifying the surface by reinforcement of composites to improve the mechanical properties and results in the ultrafine grain refinement of microstructure. FSP uses the frictional heat and mechanical deformation for achieving the maximum performance using the low-cost tool; the production time is also very less. Originality/value 100

An investigation on the influence of sintering temperature on microstructural, physical and mechanical properties of Cu-SiC composites

“…The enhancement in hardness is due to the uniform dispersion of hard SiC-reinforcement particles as well as the good bonding to matrix alloy in the composites leads to improve the hardness of the composite. The addition of a higher amount of reinforced material into matrix element results in more dislocation which also results in the increment of the hardness of the composite (Somani et al , 2018b; Gupta et al , 2020; Somani et al , 2021; Yan, 2020; Bhavya Swathi et al , 2020; Li et al , 2016; Reddy et al , 2019; Umar et al , 2021).…”

“…Optimum results were found for the sintering temperate of 800°C. Many researchers around the globe have contributed in these area (Somani et al , 2018b; Gupta et al , 2020; Somani et al , 2021; Yan, 2020; Bhavya Swathi et al , 2020; Li et al , 2016; Reddy et al , 2019; Umar et al , 2021). This technique has been developed for composite fabrication.…”

Shell and tube heat exchanger thermal-hydraulic analysis equipped with baffles and corrugated tubes filled with non-Newtonian two-phase nanofluid

“…Thus, investigation on the STHEs is needed for performance enhancement. Turbulators, obstacles, ribs, corrugations, baffles and tube geometry, and also various arrangement of these components have a noticeable effect on the STHEs thermal-hydraulic performance (Arie et al, 2020;Bezaatpour and Rostamzadeh, 2020;Nguyen et al, 2019;Atlas et al, 2020;Bhavya Swathi et al, 2019;Sindhu and Gireesha, 2020). Youcef et al (2019) conducted a three-dimensional numerical investigation presenting a new type of wing baffle.…”
