Alloy 709 was oxidized at 700 °C for 500 h in a steam environment. A microstructural analysis of the oxide scale is reported. Modern techniques of advanced electron microscopy were used to characterize the morphology of the oxide scale and recognize its single components. The material developed a complex, multilayered oxide scale. The outermost layer consisting of FeO. FeNiO tI28 spinel was detected underneath. An internal oxidation zone is present in the innermost layer. High quality SEM-EDS maps give insight into a larger area of the oxide scale at a relatively low magnification.
合金709在蒸汽环境中于700°C下氧化500小时。报告了氧化皮的微观结构分析。采用先进电子显微镜的现代技术来表征氧化皮的形态并识别其单一成分。该材料形成了复杂的多层氧化皮。最外层由FeO组成。在其下方检测到FeNiO tI28尖晶石。最内层存在内氧化区。高质量的扫描电子显微镜-能谱图在相对较低的放大倍数下可洞察氧化皮的较大区域。
