摘要 |
Solid state processing is performed on a workpiece by using a tool capable of friction stir processing, friction stir mixing, or friction stir welding, wherein solid state processing modifies characteristics of a workpiece while substantially maintaining a solid phase in some embodiments, allowing some elements to pass through a liquid phase in other embodiments, and wherein modified characteristics of the material include, but are not limited to, microstructure, macrostructure, toughness, hardness, grain boundaries, grain size, the distribution of phases, ductility, superplasticity, change in nucleation site densities, compressibility, expandability, coefficient of friction, abrasion resistance, corrosion resistance, fatigue resistance, magnetic properties, strength, radiation absorption, and thermal conductivity. |
