摘　　要：针对高温合金零部件的精密成形制造由于工艺复杂、成形效率和精度低,其微观组织、力学性能及成形精度难以协同控制的问题,采用组织调控和成形工艺优化作为实现高温合金零部件成形成性一体化制造的有效手段。作为一种高温稳定相,δ相常出现于塑性变形及热处理过程中,其析出量与形貌影响合金的微观组织及力学性能。因为零件结构及服役条件的差异,所要求的组织、性能和采取的制备工艺也不尽相同。介绍了环类、盘类及叶片类3类典型的GH4169合金零件的塑性加工技术,同时引出δ相在其中起到的作用,继而对δ相的析出、球化和溶解等演化行为及其对合金变形行为和力学性能的影响进行了阐述与总结。Aiming at the problems of complex process,low efficiency and accuracy of forming,and difficult cooperative control of micro-structure,mechanical properties and forming accuracy of superalloy parts,microstructure control and forming process optimization are a-dopted as effective means to realize forming and modification integrated manufacturing of superalloy parts.As a high-temperature stable phase,δphase often occurs during plastic deformation and heat treatment processes,and the precipitation amount and morphology of pre-cipitates affect the microstructure and mechanical properties of the alloy.Due to the differences in component structure and service condi-tions of the parts,the required microstructure,properties and processing technology are also diverse.The plastic processing technologies of ring,disk and blade GH4169 alloy parts were introduced,while also introduced the role thatδphase plays in it.Subsequently,the e-volution behavior ofδphase,such as precipitation,spheroidization and dissolution,and its influence on the deformation behavior and me-chanical properties of the alloy were described and summarized.
