Abstract: Dispersoid particles in oxide-dispersion strengthened (ODS) superalloys do not only increase the creep strength, but also suppress crack initiation during high temperature fatigue. However, irregularities in the grain structure tend to counterbalance these positive dispersoid effects by giving rise to premature material failure. These effects and their mechanisms have been studied in Inconel MA 6000 and MA 754, leading to practical conclusions for improving the mechanical properties of current ODS alloys.
