Additive manufacturing (AM) aim 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 two Haynes 282 variants: one as fabricated by EBM and one after standard heat treatment was evaluated and compared with the cast and homogenized Haynes 282. Thermogravimetric analyses during 100 h exposure at 750, 800 and 950 °C and furnace exposures at 750 and 950 °C for durations up to 1000 h were performed. The oxidation behavior was characterized as a function of temperature, microstructure, composition of the alloy and heat treatment.
