摘要	为研究GH4169合金楔横轧加工过程中动态再结晶及织构演变规律,采用金相显微镜(OM)和电子背散射衍射(EBSD)对30%,50%两种断面收缩率下GH4169合金楔横轧件表层与心部的微观组织、晶体取向及织构进行分析。结果表明:GH4169合金楔横轧加工过程中,随着动态再结晶的发生,晶体取向逐渐变得随机化分布;轧制表层大角度晶界数量较轧件心部多,轧件表层织构强度变化不大,心部织构强度明显增强;经过楔横轧变形后织构发生转动,原始态织构类型为{001}〈110〉,{111}〈110〉,{111}〈011〉,轧制后主要织构类型为{001}〈010〉,{112}〈110〉,{110}〈111〉,{110}〈112〉;GH4169合金楔横轧件动态再结晶及织构演变规律是由楔横轧特殊变形特点决定的。
其他摘要	To 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.
