Analysis of phases in superalloy and high-strength steel by combination of EDS and EBSD
In order to analyze the phases of superalloy and high-strength steel,the combination method of EDS and EBSD was adopted.The non-metallic inclusions in nickel-based master alloy were identified,and the oxide layer phases of 300M low-alloy high-strength steel were distinguished.The result showed that the mean angular deviation(MAD)of the center line inclination of the nickel-based master alloy Kikuchi band was 0.79°.The non-metallic inclusion was identified as Al2O3 by comparison with the simulation bands of selected phases in the database.After ion polishing,the phases in the 300 M steel oxide layer and their distribution could be distinguished and determined by the EBSD technology.Most phases were Fe3O4 followed by Fe2O3,and the content of FeO was extremely low.
