Predictive Relationships in Friction STIR Processing of Nickel-Aluminum Bronze

Abstract

Friction Stir Processing (FSP), a hot working materials processing technology, and various analytical and computational models for it are reviewed. A simulation is used to develop a new predictive relationship for power dissipated during FSP of Ni-Al bronze according to tool traversing velocity and rotational velocity. The model is then applied to empirical data and found to fit very well. Correlations between the cooling rate and material properties are examined. A relationship between cooling rate and ductility is found, and a predictive model is developed.
