N2 - An approach called hybrid heat-source solid-state additive manufacturing (HHSAM) for fabricating multilayer AA6061 deposition with superior properties is proposed in this paper. As compared with the traditional additive friction stir deposition (AFSD), the auxiliary induction heat-source in HHSAM effectively improves the temperature and fluidity of plastic flow, which facilitates the formation and enrichment of residual Mg2Si phases besides Al(Fe,Mn)Si, promotes the dynamic recrystallization and increases the bonding strength between layers during the deposition process. Therefore, the HHSAM depositions possess a more uniform structure, superior integral mechanical properties and corrosion resistance after heat treatment process. Moreover, HHSAMed specimens avoid abnormal grain growth (AGG) in heat treatment process, which is regularly encountered in the traditional AFSD. HHSAM method is proved to be a new solid-state additive manufacturing method with good developing prospects for fabricating alloy production with excellent properties in a high-efficiency manner.
