    摘要:

    本工作通過小實驗件獲取合金亞固溶和過固溶熱處理溫度范圍和組織性能變化規(guī)律；通過測溫實驗驗證仿真模擬的熱邊界條件；提出了一種基于實驗和有限元分析方法設(shè)計盤軸一體化鎳基粉末高溫合金渦輪盤熱處理工藝的方法。采用該方法制定并施行的熱處理工藝成功制備出大尺寸雙性能渦輪盤,其不同部位的顯微組織和機械性能得到了驗證。

    Abstract:

    In this work, temperature range,microstructure evolution and corresponding mechnanical properties of sub-solvus and super-solvus were studied through experiment specimens; Thermal mechanical boundary conditions for simulation calculation were obtained through experiments; A method for designing heat treatment process of full-sized turbine disk components based on experiment and finite element analysis was proposed. The heat treatment process developed and implemented using this method has successfully prepared a full-sized dual-microstructure turbine disk, its microstructure and mechanical properties of different parts have been verified.
