摘要
为了分析高温合金和高强度钢的物相,采用能谱仪(EDS)和电子背散射衍射仪(EBSD)联用法,鉴定镍基母合金的非金属夹杂物以及区分300M低合金高强度钢的氧化层物相.结果表明,镍基母合金菊池带中心线倾角的平均角度偏差(MAD)为0.79°,经过与数据库中各选定物相的模拟花样进行比对,非金属夹杂物鉴定为Al2O3.300M钢通过离子抛光后,利用EBSD技术能够区分氧化层中的物相并确定其分布情况,大部分是Fe3O4,其次是Fe2O3,FeO含量极少.
Abstract
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.
