The anisotropic fatigue short crack initiation and propagation behaviours of a directionally solidified (DS) superalloy CM247LC at room temperature

Autor: Yuanguo Tan, Sari Octaviani, Nong Gao, Philippa Reed

The effects of mechanical and microstructural anisotropy on short fatigue crack initiation and propagation behaviours of a directionally superalloy have been studied. An unusual result was found where the fatigue lives of specimens with grains longit
