Army Research Laboratory Aberdeen Proving Ground , MD 21005-5069 ARL-RP-423 April 2013 Effect of Initial Microstructure on the Microstructural Evolution and Joint Efficiency of a WE 43 Alloy During Friction Stir Welding


The initial microstructure plays an important role in determining the spatial and temporal evolution of the microstructure during friction stir welding (FSW). The overall kinetics of microstructural evolution is location sensitive and the effect of the process strain, strain rate and thermal cycle creates complexities. In the present study, magnesium based… (More)
