Abstract
A method of selecting a geometry for a friction stirring tool, said tool having a melting point that is higher than the workpiece material, wherein the tool is placed in motion against the workpiece to generate heat in the workpiece such that workpiece material is transported in surface features of the tool, and wherein surface features manage workpiece material flow around the tool, and wherein the tool can be used in friction stir processing, friction stir mixing, friction stir welding, and friction stir spot welding of high melting temperature materials or high softening temperature materials.
