INCLUSION INFLUENCE ON FATIGUE PROPERTY OF P/M SUPERALLOY
Through the high cycle fatigue experiment,the fatigue behaviour curves on the room temperature and 650 ℃ were obtained. With the SEM analysis of the fracture section,the results showed that the inclusion involved Al,O,Mg,Ti,Si and Y. The cracks were initiated at the inclusions. And with the increase of the dimension of the inclusion,the fatigue life of the P/M alloys decreased.
