Evaluation of Inclusions in P/M Superalloy

Abstract:

The non-metallic inclusions in master alloy, P/M superalloy and HIP powder billet were studied in this paper. The results show that the amount of inclusions in master alloy is higher than that of the superalloy powers. The EB-button analysis shows that the main non-metallic inclusions in both the master alloy and the HIP powder billet is Al₂O₃.The amount of the inclusion in master alloy is about 0.166cm²/kg and the size of most inclusions is in the range of 100μm to 200μm, while the maximum inclusion size reaches 400μm.In the P/M superalloy billet, the content of inclusion is only 0.01cm²/kg and the size of most inclusions is less than 50 μm.
