Fabrication of Al/SiCp Composite and Nano-Composite with Functionally Graded Structure Via Friction Stir Processing, M.Sc. Thesis Sharif University of Technology ; Kokabi, Amir Hossein (Supervisor) ; Bagheri, Reza (Supervisor)
Abstract
The feasibility to fabricate Al/SiCp nano-composite with functionally graded structure (FG-Al/SiCp) via friction stir processing was studied successfully in this paper. The distribution of well-dispersed nano-SiCp got a range of 6mm×3mm on the cross-section of nano-composite. A compositionally graded structure of nano-SiCp in thickness direction of the 5083Al plate was obtained via four passes of FSP. The percentage of nano-SiCp over 15%, 9% and 5% was found at the depth of 1.0mm, 2.0mm and 3.0mm, under processed surface of 5083Al rolled plate, respectively. Results show that the microhardness of FG-Al/SiCp nano-composite can reach steady 46%, 34% and 15% higher than the one of the base...
