In-situ observation of short crack growth behavior for powder superalloys with different gradient grain microstructures
The fatigue crack initiation and short crack propagation behavior of a 3rd generation powder superalloy with the different microstructures were studied by in-situ scanning electron microscope (SEM) observation. The effects of microstructures at the wheel rim (coarse grain structure), wheel centre (f...
