摘要
对P91钢的蠕变试验断裂试样和蠕变-疲劳试验断裂试样,进行了硬度测试、光学显微组织观察、透射电子显微镜观察、扫描电子显微镜观察,分析了不同试验条件下P91钢的微观损伤状态。分析结果对P91钢制蒸汽管道的金属监督和寿命评估有重要的指导作用。
To P91 steel creep fracture and creep-fatigue fracture specimens,has made hardness testing,optical microscopy observation, transmission electron microscopy, scanning electron microscopy, Analyzed on different conditions of P91 steel microscopic damage status. The analysis result has the important guide to the P91 steel steam pipe metal supervision and life assessment.
