Carbide Precipitating Behavior of Ni-Based Superalloy by Long Time Aging Heat Treatment
The carbide precipitation in the microstructure of superalloy Inconel 751 by long time aging treatment was studied.The results show that precipitation carbide of superalloy Inconel 751 is M_(23)C_6 at 700℃and MC at 850℃. Different precipitation types of carbide in the alloy are transformed in long time aging treatment,turn to M_(23)C_6 type at lower temperature and turn to MC type at higher temperature.
