The rules of equilibrium phases precipitation in typical nickel base alloy Inconel 690 (0. 015C
29. 42Cr
9. 10Fe
0. 26Ti
0. 16A1) melted by Its vacuum induction furnace + ESR process and the effect of alloy chemical composition on M23 C6 phase precipitation behavior has been studied by Thermo-Calc software. The structure of solid solution and sensitizing treated alloy Inconel 690 was tested and analyzed by SEM
TEM
SADP and EDS. Results showed that the main equilibrium precipitates in alloy Inconel 690 were M23C6 and); as solid solution temperature was 000 t
the M23 C6 dissolved completely. Calculated results indicated that the effect of carbon content in alloy on precipitation amount of M23 C6 was greater than that of other elements in alloy.
