| Abstract Scope |
Aging infrastructure is a growing issue for our waterways navigation systems. Complex castings and long lead times can lead to reductions in trade navigation and adversely affect the economy. Each structure also requires custom cast components making large scale metal additive technologies a prime candidate for infrastructure repair. To this end, this effort studies the use of wire fed directed energy deposition (DED) to fabricate large metal components critical to infrastructure repair. The structure-property-performance of the deposited mild steel (ER70S) was studied to better understand the efficacy of using the material for the replacement of a 5 ft sector gear used in a lock structure. Microstructural (optical and scanning electron microscopy) and mechanical characterization (static tension and fully reversed fatigue R=-1) were run on both the deposited material and that of a cast 5 ft sector gear for comparison. |
