Abstract Scope |
The design of modern engineering components requires the development of innovative manufacturing techniques. In parallel, design engineers increasingly design components closer to their failure limits due to sustainability and performance demands, necessitating better predictions of mechanical behavior. Additive friction stir deposition (AFSD) has emerged as a solid-state additive manufacturing method which allows for the construction of near-net-shape components. When employed with precipitate-strengthened alloys, AFSD tends to lead to a loss of material strength due to changes in the morphology of the precipitates. In our work we utilize a crystal plasticity finite element model informed by experimental material characterization and mechanical testing performed on samples before and after AFSD processing. We discuss the contribution of the crystallographic texture on the yield strength of the material and the implementation of a precipitate strengthening model used to account for the effects due to the presence of precipitates. |
