EFFECT OF ECCENTRICITY PIN GEOMETRY ON THE FABRICATION OF SURFACE COMPOSITE (AL6061-T6 /SIC) BY FRICTION STIR PROCESSING
Journal Title: International Journal of Metallurgical & Materials Science and Engineering (IJMMSE) - Year 2018, Vol 8, Issue 4
Abstract
This research investigates the effect of three types of friction stir processing (FSP) tool with a pin eccentricity of 0, 0.5 and 1mm on the fabrication of AA6061-T6/SiC surface composites (SCs). The pin eccentricity induced severe plastic deformation in the nugget zone or composite region, which resulted in the enhanced material flow. FSP experiments were performed with a constant tool speed of 1000 rpm, traverse feed of 20 mm/min and the tilt angle of 3°. The experiments revealed that 0.5mm eccentric tool produced better surface composites with uniform particles distribution and mechanical properties
