AbstractTo study the dynamic recrystallization and texture evolution of GH4169 alloy during the cross wedge rolling processing,the microstructure,crystal orientation and texture in the surface and core of the GH4169 alloy with the area reduction of 30% and 50% were analyzed by the metallographic microscope(OM)and electron backscatter diffraction(EBSD),respectively.The results show that the crystal orientation gradually tends to be random with the occurrence of dynamic recrystallization during the cross wedge rolling process of GH4169 alloy.There are more high-angle grain boundaries in the rolled surface than those in the core.No evident change of the texture intensity in the rolled surface can be observed,while the core texture intensity increases obviously.The textures have rotated after the cross wedge rolling and the previous types of{001}〈110〉,{111} 〈110〉,{111}〈011〉change to the types of{001}〈010〉,{112}〈110〉,{110}〈111〉,{110}〈112〉.The dynamic recrystallization and texture evolution of GH4169 alloy are dominated by the special deformation characteristics of the cross wedge rolling.
