Friction stir processing (FSP): refining microstructures and improving properties
MetadataShow full item record
FSP is reviewed as an allied technology of friction stir welding (FSW) and additional considerations such as processing pattern and step over distance are introduced. The application of FSP to continuously cast AA5083 material in the as-cast condition is described and the extent of grain refinement and homogenization of microstructure is documented. The FSP-induced superplastic response of this material is compared to the response of conventionally processed AA5083 and the improved ductility of the FSP material is related to grain refinement and microstructure homogenization.

Modeling of thermal and mechanical effects during friction stir processing of nickel-aluminum bronze Jamison, Jay Dee (Monterey, California. Naval Postgraduate School, 2004-09);Friction Stir Processing (FSP), although relatively simple in concept, results in an extremely complex thermomechanical treatment to the material being processed. Previous studies of FSP have shown that the process results ...
