Influencing Geometrical Parameters of Tools in Friction Stirring Technology: A Short Review

Friction stirring based “Green” processes are ruled by geometrical and process aspects of the tools used for generating desired properties in the processed materials. Considering only geometrical aspects, the developments in tool geometry, its modifications with the time, profiles and their corresponding impacts on the property generation are addressed in the present work. It is a censorious and judicious review which consolidates the relevant information apropos of all geometrical aspects of tools and their roles in property generation.
