摘要:
Directionally solidified gas turbine blades are wildly used in land-based industrial gas turbines for power generation. During long-term service, the harsh service environment causes microstructural and mechanical deterioration of the blades. In order to increase usage and save costs, this study analyzed the microstructure damage in different sections of the blade. Meanwhile, this investigation discussed the optimum rejuvenation heat treatment parameter and applied it to the serviced blade for the lifetime extension. The microstructural analysis indicated that the appropriate solution temperat...
