摘要
本研究采用模拟实际载荷谱的力学试验,结合断口形貌分析,建立了在保载条件下的火力发电厂主蒸气管道材料12Cr1MoV钢的疲劳蠕变交互作用断裂特征图。并在此基础上获得作为寿命预测依据的蠕变断裂寿命和保载时间的依赖关系,为电厂安全运行提供可靠依据。
A fatigue-creep interaction fracture map for a 12Cr1MoV heat resistant steel with holding load has been constructed, by simulation tests under practical load spectrum, together with its fractographic analysis. Based on the map a relationship between creep life and holding time, has been suggested as life prediction criterion to provide a reliable base for safe operation of thermal power plant.
