摘要	Microstructure evolution of a single crystal nickel-base superalloy during heat treatment and tensile creep at 1010℃ and 248 MPa for 30h was observed and analyzed. Internal stresses because of lattice mismatch between γ and γ' phase provided the driving force for γ' shape evolution during heat treatment. More than 65 vol. % distorted cubic γ' phase keeping coherency with the γ matrix precipitated after solution at 1295℃ for 32h. The shape of γ' phase was perfectly cubic with increasing precipitate size during the two-step aging treatment. Due to the applied stress and intemal stress field the continuous γ-γ' lamellar structure perpendicutar to the apptied stress was fonmed after 30h tensile creep.
