Surface Modification of AA 6351 for Improvement of Mechanical Properties Using Friction Stir Processing

  • 327 Accesses

Part of the Lecture Notes on Multidisciplinary Industrial Engineering book series (LNMUINEN)


Friction stir processing (FSP) is originated from friction stir welding (FSW); this technique produced by “The Welding Institute” of UK. FSP is a new method to change the microstructure and properties of workmetal by using frictional power, and it has become a powerful tool for homogenizing the structure, grain refinement and the mechanical properties improvement. In the present investigation, SiC particles were merged in workmetals ALUMINIUM ALLOY6351(AA6351) by using FSP, to create surface layers of the particulate composite. The effects of rotational speed and traverse speeds on particle distribution and microstructures were studied. Observations were carried out by using optical microscopy of the modified surface for microstructure. Mechanical properties like tensile strength and microhardness were also assessed. The result displayed that increasing the rotational speed improved the uniform distribution of SiC particles. The hardness of the introduced composite surface was also improved. The produced composite surface has high tensile strength compared to unprocessed base workmetal.
