TL;DR: In this paper, local stirring using a friction stir processing (FSP) tool is shown to very significantly increase the fracture strain of the Al alloy 6056 sometimes by more than a factor of two while making it more isotropic.

TL;DR: In this article, an overview of the potential for superplasticity of aluminum alloys using friction stir processing (FSP) is provided, which is a variant of friction stir welding (FSW), and FSP is an effective technique to alter the metallurgical and mechanical properties of the material.
Abstract: This article provides an overview of the potential for superplasticity of aluminum alloys using friction stir processing (FSP). FSP is a variant of friction stir welding (FSW), and FSP is an effective technique to alter the metallurgical and mechanical properties of the material, which results in superplastic properties at high strain rate and low temperature. This makes FSP as an attractive and cost-effective method to produce superplastic materials. A detailed summary of previously reported superplasticity in all aluminum alloys using FSP is tabulated in this review. It reveals the influence of tool design, machine variables, number of passes, active cooling, grain size, superplastic temperature, strain rate, and elongation on the superplastic properties of FSP aluminum alloys. Variants of FSP to achieve superplasticity at optimized conditions are proposed based on dual rotation of tool and additional cooing during the process. Applications of superplastic forming in aerospace and automotive are discussed. The direction of research in friction stir-processed superplasticity is covered in future scope.

TL;DR: In this paper, an as-rolled Mg-Nd-Zn alloy was subjected to FSP and the microstructure in the processed zone of the FS-400 rpm alloy exhibited refined grains, a more homogenous grain size distribution, less second phases, and stronger basal plane texture.

TL;DR: In this article, single-walled carbon nanotubes (SWCNTs) were added to aluminium using friction stir processing (FSP) to survive the thermal and stress cycles involved with FSP.
Abstract: Single-walled carbon nanotubes (SWCNTs) were added to aluminium using friction stir processing (FSP). The SWCNTs survived the thermal and stress cycles involved with friction stir processing. The Raman spectroscopy and SEM results are presented. Potential applications of nanotubes inserted into metals by this method are discussed.
