    | Abstract Scope | 
    
Additive manufacturing (AM) aims to complement or replace conventional and costly machining or production processes. While the current focus is on the evaluation of mechanical properties of as-fabricated or heat-treated materials, the oxidation behavior of AM materials is rarely investigated. The oxidation behavior of three Ni-based superalloys fabricated by EBM or SLM was evaluated and compared with the wrought materials. Thermogravimetric analyses and cyclic exposures up to 950 °C for durations up to 5000 h were performed. Alloy microstructure and powder composition were found to strongly influence oxidation behavior and material degradation processes. |
