Chemical redistribution and change in crystal lattice parameters during stress relaxation annealing of the AD730 TM superalloy
Durand, Malik; Cormier, Jonathan; Paumier, Fabien; Katnagallu, Shyam; Saksena, Aparna; Kontis, Paraskevas; Pettinari-Sturmel, Florence; Hantcherli, Muriel; Franchet, Jean-Michel; Dumont, Christian; Bozzolo, Nathalie (Peer reviewed; Journal article, 2022)The present study aims to understand the underlying mechanisms of macroscopic contraction that occurs in γ/γ′ nickel based superalloys submitted to isothermal annealing and resulting in stress relaxation retardation. Samples ... -
The effect of γ matrix channel width on the compositional evolution in a multi-component nickel-based superalloy
Saksena, Aparna; Kubacka, Dorota; Gault, Baptiste; Spiecker, Erdmann; Kontis, Paraskevas (Peer reviewed; Journal article, 2022)High-temperature diffusion affects the long-term stability of superalloys and hence their service life. Yet, details of the mechanisms remain elusive. Here, the γ-γʹ microstructure itself is used as a nanoscale diffusion ...
