Identification of the partitioning characteristics of ruthenium in single crystal superalloys using atom probe tomography

Two experimental Re-containing single crystal superalloys, one doped with Ru, are studied using atom probe tomography. This has allowed the partitioning coefficient of Ru to be determined, and the effect on the partitioning characteristics of the alloying elements Cr, Al, Re, Co, Ta, Hf and W to be...

Zusammenfassung:	Two experimental Re-containing single crystal superalloys, one doped with Ru, are studied using atom probe tomography. This has allowed the partitioning coefficient of Ru to be determined, and the effect on the partitioning characteristics of the alloying elements Cr, Al, Re, Co, Ta, Hf and W to be identified.
