摘要	The mechanical properties of GH4169 alloy sheet after cold rolling (at 0%, 10%, 30%, 50% and 70%) and solid solution were investigated. The textures and Taylor factors were characterized using electron backscattering diffraction (EBSD). The fractions of delta phase were measured by X-ray diffraction. The contributions of delta phase, grain size, texture, and work hardening on the mechanical properties were also discussed. The results showed increases in the yield strength (YS) (0.2%) as well as the ultimate tensile strength (UTS) of GH4169 superalloy sheet after cold rolling, when rolling reduction was increased. In contrast, following solid solution treatment, YS and UTS were increased then subsequently decreased. The changes of yield strength of GH4169 superalloy were attributed to the texture and work hardening, followed by the grain refinement and precipitation of delta phase. When the rolling reduction was below 30%, the influence of delta phase was greater than grain refinement and when the rolling reduction was larger than 50%, the controversial results occur. The precipitation of delta phase promoted the improvement of yield strength, the relationship between the fraction of delta phase and improved yield strength satisfactory fit to the following equation: sigma(delta) = 15.9W(delta)+ 59.7.
