Abstract

In many applications, additive manufacturing techniques are rising to build, layerby-layer,component with complex shapes and specific microstructures. DirectMetal Deposit (DMD) process allows to tune the material's composition usingdifferent powder feeder. In this study, we focused on a gradient from a 316Laustenitic stainless steel to a 9Cr-1Mo martensitic steel. These steels are widelyused for nuclear applications, but due to their chemical composition differences,welding them is uneasy. In this study, microstructures obtained by Tungsten InertGas welding are compared with graded parts obtained by powder metallurgy, afterSpark Plasma Sintering or additive manufacturing with Direct Metal Depositprocess.
