| Abstract: | The compatibility of the HT superalloy GH4169 with the dinitrogen tetroxide propellantis tested based on the method of the compatibility experiment. The mechanical properties, the surface condition and the composition changes of the GH4169 specimen are compared after being soaked in the dinitrogen tetroxide. It is found that the compatibility of the GH4169 with the dinitrogen tetroxide can meet the service requirements, and the class-I compatibility criteria are satisfied within a soaking test period of one year. |
