Abstract

Abstract: Friction stir processing (FSP) is developed for the usage aluminum alloys and it is metal processing method that can provide grain structure of microstructures. Due to the frictional processing heat and stir processing the microstructure of the foundation metal is changed. The Silicon Nitride (Si3N4) and Aluminium Nitride (AlN) are used as reinforcement with the base metal Al2024 by using friction stir processing. Hardness, corrosion resistance, micro structure formation wear resistance and durability of Al2024 have been increased in this friction stir processing by reducing the defects due to the melting of the metal. It is an excellent material processing technology, and there is a high possibility for the preparation of super plastic materials and metal matrix composites. This work is mainly to improve the mechanical properties of Al2024 while it is reinforced by Si3N4 and AlN. Thus the results from this investigation is explained and discussed.
