This paper [1] has been retracted as it is essentially identical in content with the published article " Elucidating of rotation speed in friction stir welding of pure copper: Thermal modeling " published in References [1] M. Jabbari and C. C. Tutum, " Optimum rotation speed for the friction stir welding of pure copper, "

friction-stir welding process is a novel method of solid state welding, which produces heat due to friction between the pin, the shoulder and the workpiece. this heat causes a paste area. shoulder pressure and pin spin cause edges integration and lead to welding. in this study, firstly, the feasibility of welding of steel sheet (en10130) with a thickness of 1.5mm has been tested by 58 experimen...

In this investigation, the effect of friction stir processing (FSP) parameters such as rotational speed, traverse speed and plunge depth on the tensile strength of AA6063 aluminum alloy was studied. The experiments were carried out as per response surface methodology parametric design concepts to study the influence of various combinations of process parameters. Statistical optimization techniq...

Ultra-fine grained (UFG) structure (~0.6 µm) was produced in the stir zone (SZ) of 6061-T6 aluminum alloy joints using friction stir processing (FSP) cooled by liquid nitrogen (N2). A new experimental set-up was used to simultaneously quench the lower and upper surfaces of the samples during the processing. In addition, FSPed joints, using a steel backing plate, were produced at room temperatur...
