Frequently, multiple material properties such as extreme corrosion resistance and high strength are necessary within the same component but may not be feasible with a single material. Due to the strong correlations between material selection and the difficulty of manufacturing with component cost, expensive material use must be limited. It can be highly beneficial to manufacture a component which uses specialty steel grades only where necessary, and utilizes more affordable, commonly available steels for bulk structural support. A functionally graded structure is fabricated using pulsed wire arc additive manufacturing to showcase the capabilities of such a material. This is accomplished by layering high strength low alloy steel (HSLA-100) on top of duplex stainless steel (ER2209). The resultant morphology is investigated, and characterization of the functionally graded material is performed. Mechanical testing coupled with DIC allows for elucidation of mechanical properties and visualization of stress concentrations at the functionally graded interface.
