The changes occurring in two heat-resistant alloys while aged at 750 °C for different periods of time were studied. Aging promoted precipitation of secondary M_(23)C_6 carbides and transformation of Nb-rich, which were evaluated by SEM. The results show that transformation of the NbC starts from their boundaries to their centre by silicon diffusion; carbon was detected to migrate from these particles promoting precipitation of secondary Cr-rich carbides in regions adjacent to the Nb-rich particles.
