In this work, the velocity of crack propagation at high temperature was investigated with da / dt - C t relationship using recently developed P92 and P122 steels. Role of cavity in crack growth rate and load line displacement rate was studied by measuring the cavity size and density, which will influence crack nucleation and growth. Since temperature and stress changes are particularly important at high temperature, crack growth behavior was evaluated under various temperature and K i(initial stress intensity factor). Effect of Cr content was evaluated by measuring crack growth activation energy in thesis.
