Fig. 9: Schematic evolution of element enrichment (i.e., Re) at SF and PDs during creep.
From: Unveiling the Re effect in Ni-based single crystal superalloys
a Schematic showing the generation of SFs by PDs inside of γ‘ phases with segregation in the dislocations in the γ phase. Further analysis focuses on the dashed rectangle region of a PD and associated SF. b 5% creep strain: Re Cottrell atmosphere around PD and less enrichment of Re in the SF. c Rupture: decreased amount of Cr and Co segregating to the PDs compared to the 5% creep stage, no Re enrichment observed and less dragging effect at this stage.
