Abstract Scope |
Additive manufacturing of metallic components has gained considerable attention among researchers in the last few years. A lot of research has been focused on optimizing both the process parameters for different AM techniques and the mechanical properties of AM components. But, so far very little has been published about high temperature degradation of metallic AM materials. In this work we report on high temperature oxidation behaviour of AM FeCrAl and Ni-based alloys. In particular, the influence of microstructure and crystallographic texture on their high temperature oxidation properties is studied in detail by advanced analytical electron microscopy techniques such as STEM/EDX and SEM/EBSD/TKD. The results are compared with materials produced by conventional methods. It will be demonstrated that while the overall oxidation behaviour of AM and conventionally produced FeCrAl alloys is comparable, the unique microstructure and crystallographic texture of the AM material locally influences the oxidation kinetics. |
