- Abstract:
-
The high-temperature sustained load crack growth behaviour of a Ni-base superalloy was investigated using a combination of mechanical testing in controlled atmosphere, fractographical and microanalytical investigations, and finite element modelling. The results show that the local crack front geometry is un-even on two scales - jaggedness on the scale of 100. μm was observed in all specimens, whereas mm-scale waviness could occasionally be observed. The jaggedness can be explained by a percol...
