On the coarsening mechanism and deformation of borides under annealing and creep in a polycrystalline superalloy

Lola Lilensten, Aleksander Kostka, Sylvie Lartigue-Korinek +4

We have investigated the coarsening mechanism of intergranular Cr-rich M2B borides after creep and annealing at 850C for approximately 3000 hours in a polycrystalline nickel-based…
