Abstract：

Ru　is　crucial　in　improving　creep　properties　in　Nickel-based　single-crystal　superalloys.　The　effect　of　Ru　content　on　the　creep　behavior　of　nickel-based　single-crystal　superalloy　was　studied.　Ru　exhibits　unprecedented　mechanical　properties,　increasing　the　creep　life　at　1120　degrees　C　but　decreasing　it　at　1180　degrees　C.　This　is　due　to　the　competition　in　the　stress　concentration　formed　between　the　topologically　closepacked　phases　and　the　creep　cavity.　They　are　both　related　to　the　dissociation　of　the.　gamma　phase.　The　effect　of　oxidation　caused　by　the　addition　of　Ru　is　lower　than　these　two　factors.　This　work　helps　to　recognize　the　comprehensive　effect　of　Ru　and　can　provide　guidance　for　alloy　design　in　the　future.
