How many passes are required to develop a composite with perfect interface bonding in MMC joint that is fabricated by friction stir welding?

12 December 2013 1 3K Report

Indeed, we want to fabricate reinforcement joint by addition of Nano-particles like alumina. The base materials are 5xxx & 7xxx aluminum series. We want to know how many passes is needed to preventing agglomeration of particles. On the other hand, what is the optimum number of passes to reach a perfect joint with homogeneous particles distribution?

R. Sathiskumar

Two to four passes are needed to achieve homogeneous distribution without any agglomerations.
