Evaluation of Inclusions in P/M Superalloy
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.
