EXPERIMENTAL INVESTIGATION ON FRACTURE TOUGHNESS OF INERTIA FRICTION WELDED NICKEL-BASED SUPERALLOY
In the present study, the fracture toughness in terms of crack tip opening displacement (CTOD) of inertia friction welded superalloy has been evaluated. The CTOD testing of base metal and weld metal were conducted using single-edge notched bending specimens at room temperature (22℃) and elevated temperature (650℃) respectively. Critical CTOD values were calculated from the corresponding load-CMOD curves. The fracture toughness properties of different regions at different temperatures were evaluated. Fundamental data are provided as references for engineering research and application.
