TENSILE CREEP DEFORMATION AND DAMAGE BEHAVIOR IN A NICKEL-BASE SUPERALLOY AT 900℃ H.C.Yu1,H.C.Yang2,S.S.Xie3 (1.Beijing Institute of Aeronautical Materials, Beijing 100095, China;2.College...-base superalloy at 900℃/170MPa were investigated. At the first creep stage, abnormal creep occured due to the resolution of fine particles, and the deformation initiated from grain boundary areas......
Finite element analysis of γ′-phase raft mechanism in Ni-based single crystal superalloy WU Wen-ping(吴文平), GUO Ya-fang(郭雅芳), WANG Yue-sheng(汪越胜) Institute of Engineering Mechanics... in a single crystal Ni-based superalloy with the [001] orientation. The results show that the creep and rafting are closely related with the stress and strain energy density distributions in the matrix......
