.... After ~2000 h, the situation was reversed with significant spallation observed for the wrought HX alloy only. Low mass gains were observed for the EBM N07247 alloys at 950°C, but thick oxide scales were observed locally due to the presence of oxidized cracks. Massive oxidation of these cracks led...
