摘      要：The aim of present work is fabrication of Al/Al2Cu in situ nanocomposite by friction stir processing(FSP)as well asinvestigation of FPS parameters such as rotational speed,travel speed,number of FSP passes,and pin profile on the microstructure,chemical reaction,and microhardness of Al based *** Al2Cu particles were formed rapidly due to mechanicallyactivated effect of FSP as well as high heat generation due to Al?Cu exothermic *** microstructure of the nanocompositesconsisted of a finer grained aluminium matrix(~15μm),unreacted Cu nanoparticles(~40nm),and reinforcement nanoparticles *** morphology of Al2Cu is attributed to the local melting during *** diameter has a higher effect on themicrostructure and hardness *** hardness measurements exhibited enhancement by57%compared with the base metal.
