Research on micro strain and sub grain size of each texture in 6A16 Al sheet

Abstract

Abstract The micro strain and sub grain size of each texture type in cold rolled 6A16 Al alloy sheet were calculated using X-ray line broadening method, and the effects on the texture transformation during recrystallization process were investigated. The results showed that strain in R/S was the largest, and Brass, Copper, Goss in sequence, the sub grain size in R/S was the least, and Brass, Goss, Copper in sequence, which was coincident with the texture transformation speed during solid solution process, meanwhile, the contents of recrystallization texture, such as R/S, Cube and CubeND20 reduced obviously as the cold rolling stored energy released when recovery process imported before solid solution. It was conformed that the recrystallization texture transforming was influenced by stored energy significantly.
