Book Description :

The use of friction stir processing to locally modify the microstructure to enhanced formability has the potential to alter the manufacturing of structural shapes. There is enough research to put together a short monograph detailing the fundamentals and key findings. One example of conventional manufacturing technique for aluminum alloys involves fusion welding of 5XXX series alloys. This can be replaced by friction stir welding, friction stir processing and forming. A major advantage of this switch is the enhanced properties. However qualification of any new process involves a series of tests to prove that material properties of interest in the friction stir welded or processed regions meet or exceed those of the fusion welded region (conventional approach). This book will provide a case study of Al5083 alloy with some additional examples of high strength aluminum alloys. Demonstrates how friction stir processing enabled forming can expand the design space by using thick sheet/plate for applications where pieces are joined because of lack of formability Opens up new method for manufacturing of structural shapes Shows how the process has the potential to lower the cost of a finished structure and enhance the design allowables

Book Description :

The widespread industrial use of magnesium alloys as a structural material is often limited by their poor room temperature formability, resulting from the low symmetry of readily available slip systems. Controlled microstructural and textural modifications, imposed by severe plastic deformation processes, have the ability to reduce the anisotropy and fur- thermore increase the ease of activating basal slip. Such modifications have been realized by friction stir processing (FSP), a derivative of friction stir welding, which can be used to impose the necessary amounts of massive local deformation without altering the shape of a structural component. In the present study, FSP has been conducted at industri- ally viable speeds of up to 20 m/min. A numerical thermal model, calibrated by thermo couple measurements, has been adapted to predict the thermal evolution in the center of the process zone in order to gain insight into the occurring recrystallization processes. The model predicts the resulting temperatures and corresponding cooling rates to be suf- ficiently high for dynamic recrystallization processes to take place as well as to prevent annealing after processing, respectively. In combination with metallurgical investigations, these results provided the foundation for a knowledge-based selection of suitable process- ing parameters within the investigated parameter range. Micromechanical and textural investigations revealed the stir zone to be particularly suited for enhanced formability. The effect of different processing conditions on the mechanical response of the stir zone has been evaluated by micro flat tensile tests showing an increase in ductility with rising processing speed, surpassing the base material values by over 80%. Additional texture investigations revealed that the observed increase can be ascribed to the continuous align- ment of the basal planes with the macroscopic shear plane, represented by the shear layer, which is surrounding the tool. It has further been shown that the geometry of the shear layer can be controlled using suitable processing parameters resulting in the ability to tailor the texture of the material, and thus its ductility. Finally, this knowledge has been transferred to process larger areas out of which formability specimens have been prepared. The evaluation of the processed as well as base material specimens has been conducted at ambient temperature, in which information obtained from a digital image correlation system has been used to establish forming limit curves. The results show a significant improvement in formability and a decrease in anisotropy of the processed over the base material.

Book Description :

This book describes the fundamentals and potential applications of ‘friction stir superplasticity for unitized structures’. Conventional superplastic forming of sheets is limited to the thickness of 3 mm because the fine grained starting material is produced by rolling. Friction stir superplasticity has grown rapidly in the last decade because of the effectiveness of microstructural refinement. The thickness of the material remains almost constant, and that allows for forming of thick sheets/plates, which was not possible before. The field has reached a point where designers have opportunities to expand the extent of unitized structures, which are structures in which the traditional primary part and any supporting structures are fabricated as a single unit. With advanced optimization and material considerations, this class of structures can be lighter weight and more efficient, making them less costly, as well as mechanically less complex, reducing areas of possible failure. Discusses how friction stir processing allows selective microstructural refinement without thickness change Demonstrates how higher thickness sheets and plates can be superplastically formed Examples are presented for aluminum, magnesium and titanium alloys Covers the production of low-cost unitized structures by selectively processing cast sheets/plates

Book Description :

This book describes the fundamentals of residual stresses in friction stir welding and reviews the data reported for various materials. Residual stresses produced during manufacturing processes lead to distortion of structures. It is critical to understand and mitigate residual stresses. From the onset of friction stir welding, claims have been made about the lower magnitude of residual stresses. The lower residual stresses are partly due to lower peak temperature and shorter time at temperature during friction stir welding. A review of residual stresses that result from the friction stir process and strategies to mitigate it have been presented. Friction stir welding can be combined with additional in-situ and ex-situ manufacturing steps to lower the final residual stresses. Modeling of residual stresses highlights the relationship between clamping constraint and development of distortion. For many applications, management of residual stresses can be critical for qualification of component/structure. Reviews magnitude of residual stresses in various metals and alloys Discusses mitigation strategies for residual stresses during friction stir welding Covers fundamental origin of residual stresses and distortion
