High-cycle fatigue behaviour and crack growth mechanism of Ni-base single crystal superalloy under intermediate temperature
This study investigates the high cycle fatigue behaviour of a Ni-base single crystal superalloy under 760 °C and 850 °C. At 760 °C, the crack initially grows in the crystallographic shearing mode and the crack tip propagation mechanism is non-crystallographic mode. Furthermore, near the crack tip pr...
