TL;DR: In this paper, a tool capable of friction stir processing, friction stir mixing, or friction stir welding is used to modify the characteristics of a workpiece while maintaining a solid phase in some embodiments, allowing some elements to pass through a liquid phase in other embodiments.
Abstract: Solid state processing is performed on a workpiece (16) by using a tool (10) 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

Abstract: In this study, a detailed analysis of friction stir-based processes that can significantly contribute to joining of materials and surface property enhancement has been completed. Past, present, and future projections, advantages and disadvantages, technological barriers, and drawbacks of these processes have been given. Detailed explanations of the recent developments of friction stir-based processes and main components are given. Potential industrial applications have been assessed and evaluated using economic and technological considerations. In industrial applications, friction stir-based processes can be used in conjunction with additive processes such as laser-engineered near net shaping, thermal spraying and laser-assisted direct metal deposition processes. Developments in friction stir-based processes have led to improved metallurgical and mechanical properties such as microstructure modification, refinement, homogenization, surface cladding, corrosion, fatigue, wear, and hardness of metallic materials. The results of the study conclusively predict that reasonable costs and improved properties of processed materials will lead to a substantial increase in the use of friction stir-based processes.

TL;DR: In this paper, two post-spray treatments, i.e., high-temperature vacuum annealing (HTVA) and friction stir processing (FSP), were employed to modify the cold-sprayed (CS) Ni-Ti coatings, obtained from a mechanically blended powder.
