Abstract Scope |
The effects of forging on the microstructure and mechanical properties of AISI 316LSi produced via Wire Arc Additive Manufacturing (WAAM) were investigated in this work, using Cylindrical and novel Double Cone samples. Large-scale deposits (10” x 7” x 2.5”) of AISI 316LSi were prepared in collaboration with Lincoln Electric Additive Solutions using their WAAM robot cell and revealed significant anisotropy of properties. The source(s) of anisotropy in as-deposited material and their effects on the double cone results will be shown and modeled. Changes in microstructure in the compressed double cone samples will be shown that include the grain size, ferrite content, and local mechanical properties (e.g. hardness) for two different orientations (Deposition direction – X axis and Building direction – Z axis). |
