On The Fatigue Short Crack Behaviors of Directionally Solidified Superalloy DZ4 by <i>In Situ</i> SEM Observations

, 2010
Small fatigue crack behaviors in a nickel-based directionally solidified superalloy DZ4 were studied by in situ scanning electron microscopy. The crack initiation and propagation manners were identified under different temperatures, i.e.
