| Abstract Scope |
The effects of changes in process parameters on the microstructure and mechanical properties of AISI 316LSi produced via Wire Arc Additive Manufacturing (WAAM) will be reported. 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. The effects of changes in process parameters (Heat Input and Interpass Temperature) on the microstructure, ferrite content, corrosion, and mechanical properties (Tension, Impact, and Fatigue Crack Growth) of the deposits will be reported for all three orientations, along with measurements of surface roughness on the as-deposited conditions. |
