| Abstract: | A new phase stability prediction method,REN,for nickel base single crystal superalloys was proposed. This method was applied to predicting the phase stability of fifty nine reported nickel base single crystal superalloys in literatures. Compared with experimental data and the results predicted by Mdt method, the prediction accuracy of REM method was higher,the REM method can successfully predict TCP precipitation trend of nickel base single crystal superalloys. |
