Abstract

This work investigated the oxide cracking behavior of 18%Cr austenitic steels. The role of voids at the duplex oxide layer interface has been discussed. Simulation results demonstrate that the stress concentration facilitates the crack nucleation at the void top. Interestingly, the interface of the duplex oxide layer exhibits better cracking resistance. Experiment results confirm that the voids facilitate cracking when the temperature drop is beyond 119 °C during oxidizing at 650 °C for TP347H alloy. By comparing, more than 290 °C of temperature drop is needed for the cracking on TP347HFG alloy, which is because the void diameter is small.
