Short crack initiation and growth at 600 °C in notched specimens of Inconel718

, 2003
The natural initiation and growth of short cracks in Inconel®718 U-notch specimens has been studied at 600 °C in air. U notches were introduced through broaching, and hardness traces and optical microscopy on cross-sections through the U notch broaching ...
