Crack Growth Rate of Superalloy Turbine Disks

    Graphical Abstract
    • Abstract
  • Crack growth rate of superalloy turbne disks is tested by means of direct current-voltage.The results show that the CGR of superalloy turbine disks is decided by stress rupture duchlity, not by strength of superalloy and the valuahon of CGR is determinned by the incline of curve and the range of stress strength factor.
