摘要

本文介绍了用于固体氧化物燃料电池(sofc)关键部件金属互连的Crofer 22 APU钢的物理化学和力学性能的研究结果。对非金属夹杂物和基体进行了显微组织和硬度研究。通过对Crofer 22 APU原料和钢在800℃空气中循环氧化600 h后的压缩试验,确定了非金属夹杂物的组成及其对钢强度性能的影响。

PHYSICOCHEMICAL AND MECHANICAL PROPERTIES OF CROFER 22 APU FERRITIC STEEL APPLIED IN SOFC INTERCONNECTS
The paper presents the results of investigations of the physicochemical and mechanical properties of the Crofer 22 APU steel designed for application in metallic interconnects forming the key components of solid oxide fuel cells (SOFCs). Microstructural and hardness studies of non-metallic inclusions and the matrix were carried out. Based on compression tests of raw Crofer 22 APU and the steel after 600 hrs of cyclic oxidation in air at 800°C , the composition of non-metallic inclusions and their influence on the strength properties of the steel were determined.
