Abstract Scope |
In this research, we study the feasibility of using additive friction stir deposition (AFSD) as a suitable technology for repairing cracks in 304L stainless steel canisters. Multiple layers of 304L materials were deposited on a 304L plate. Tensile specimens were extracted from the deposited component in longitudinal and build direction to evaluate tensile strength and to characterize microstructure evolution. The AFSD component were dense and exhibited a highly refined grain structure as compared to the feedstock. Continuous bonding at the interfacial layers were observed with no evidence of cracks or porosity. The present study indicates AFSD technology can be implemented for effective repair of 304L stainless steel canisters. |
