Abstract：

Based　on　the　tensile　stress-dominated　low　cycle　fatigue　(LCF)　tests　at　760°C,　the　fracture　morphology　of　a　second-generation　Ni-based　single　crystal　superalloy　(SC)　was　studied　in　this　paper.　It　was　found　that　under　LCF　loading　the　specimen　cracked　with　one　fatigue　source.　The　angle　of　fatigue　bands　in　crack　propagation　region　was　related　to　the　secondary　orientation　deviation　from　crystal　orientation　[100].　In　addition,　evidence　showed　that　the　specimens　fractured　along　the　slip　surface　of　{111}　octahedral　slip　systems.　©　Published　under　licence　by　IOP　Publishing　Ltd.
