Additive manufacturing enables the production of parts showing locally different properties by altering the incremental motive design – such as FCC or BCC mimicking lattices, on the geometry to maximize the exploitation of their performances for structural purposes. The changes at the smaller scales can further alter the properties by changing the local composition, resulting in functionally graded materials. For this purpose, we have investigated the transition of crystal structure by adding Cr element to the equimolar CoCrFeMnCu alloy using arc type of direct energy deposition (arc-DED) additive manufacturing process. We have used empirical and CALPHAD models to predict the transition behavior; XRD, EBSD, TEM, and SEM analyses for the characterization of phases and microstructure on the compositional-graded geometry build by arc-DED. The microstructural hierarchy and functional mechanical properties of the arc-DED process parameters will be discussed in detail.
