| Abstract Scope |
Wire feedstock laser metal deposition (WFLMD) is proposed to have several advantages over other metal additive processes in energy materials applications. These advantages include lower feedstock cost, low waste, improved mechanical properties, improved microstructure, and high deposition rate. For adoption of WFLMD in energy and other high value applications, mechanical properties and accompanying microstructure must be assessed and optimized. The goal of this work is to compare properties of 316L stainless steel produced by LMD under both shielding gas deposition and vacuum conditions. The WFLMD process is discussed. Hardness mapping, tensile strength, and microstructure are compared to conventionally processed 316L and 316L deposited via other AM techniques. |
