Abstract Scope |
Additive manufacturing (AM) methods produce materials that have been subjected to complex thermal cycles and histories. A Gleeble Thermomechanical Simulation System has been used to replicate the thermal history from several locations in directed energy deposition (DED) builds. Using results from these simulations, build height and thermal history have been correlated with microstructure and mechanical properties. A series of stainless steels have been analyzed with this methodology, including S32101, S32205, S32750, and S30400. These alloys were chosen for their excellent corrosion resistance and have a range of microstructures, compositions, and mechanical properties. |
