This paper provides the first description of residual stress distributions in a 66-mm-thick
AA6061 deposit produced by additive friction stir deposition (AFSD). The AFSD process is
being quickly developed as a solid-state additive manufacturing technique. Residual
stresses in additively manufactured components can affect the susceptibility to fracture and
fatigue, so there is a need to understand the residual stress distributions in the AFSD
deposits. In this research, a large (194× 49× 66 mm) AA6061 deposit was produced using …
