Small fatigue crack propagation from micronotches in the cast aluminum alloy W319

Abstract A methodology of creating defects in a cast aluminum alloy, using femtosecond pulsed lasers has been described. Small fatigue crack growth behavior of cracks initiated from these defects was examined as a function of temperature. The variation in growth rate with temperature was related to the extent of crack-tip plasticity.
