摘要	The LCF behaviors of two Ni-based single-crystal superalloys at room temperature and 600 degrees C have been studied. Superalloy with 3 wt% Ru-containing (3Ru alloy) had more excellent fatigue performances than that of non-Ru superalloy (0Ru alloy). Microstructures observed by transmission electron microscope showed that 0Ru alloy exhibited slip bands with orthogonal slip directions after the test. (1 (1) over bar1) [011] and (1 (1) over bar1) [0 (1) over bar1] slip systems were activated in plastic deformation process. While (111) [0 (1) over bar1] and (1 (1) over bar1) [0 (1) over bar1] slip systems of 3Ru alloy were along the single slip direction. Therefore, adding alloying element Ru to the superalloy promoted uniform deformation and prolonged fatigue life. (C) 2019 Acta Materialia Inc Published by Elsevier Ltd. All rights reserved.
