Properties Augmentation of Cast Hypereutectic Al–Si Alloy Through Friction Stir Processing

Abstract The present endeavour is to augment mechanical attributes via friction stir processing (FSP) in hypereutectic aluminium–silicon castings by the means of microstructural modifications and defects reduction. Wherein, study proceeds with mainly two approaches namely, alteration tool revolution (TR) number FSP passes. prepared specimens were evaluated investigating volume fraction porosities, characterizations microhardness. Therefrom, specimen highest passes delivered most uniform properties resulting from reduction casting porosities refined silicon particle distribution throughout processed zone. This may be considered as a footstep towards more industrial readied material transformation. Graphical
