Influence of Thermal Exposure Temperature on Surface Oxidation of Ti-20Mo Superalloy Used for Electric Power AITranslate
Abstract AITranslate
In order to further improve the oxidation resistance of Ti-20Mo alloy,the surface oxidation and microstructure evolution of Ti-20Mo superalloy used for electric power were studied at different thermal exposure temperatures.The results show that there are equiaxedαgrains and a large number of lamellarα+βeutectic microstructure in the original alloy.When the samples are exposed at 200℃and 400℃,their weight gain is less than 6mg.When the thermal exposure temperature is 600℃,the oxidation weight gain of the sample increases approximately linearly,and finally reaches 16.1mg.The increase of thermal expo-sure temperature can help the alloy to faster complete the recovery and recrystallization transformation process and achieve the purpose of fine grain strengthening.The equiaxedαcrystal grains and the lamellarα+βeutectic microstructure are formed in the thermally exposed alloys.With the increase of temperature,the grain size obviously increases and the grain distribution becomes more uniform.A large number of fine microstructures are precipitated in the grain boundary at 600℃.The microstructure of original Ti-20Mo alloy consists ofαphase and TiO2 phase,and more TiO2 phase is generated with the increase of thermal exposure temperature.When the thermal exposure temperature is 200℃or 400℃,TiO2 is formed in the alloy oxide film.When the temperature rises to 600℃,Al2O3 is formed in the alloy oxide film.
