摘要
采用先进的分析测试手段对12Cr1MoV水冷壁的珠光体耐热钢管失效后组织及硬度的变化进行连续分析,以便更加准确地判断其失效原因。结果表明,12Cr1MoV水冷壁爆管原因为短时超温;组织自背火侧至向火侧依次为F+P,F+S+P,F+B,F+M+T,M+T,同时其硬度也呈现逐渐升高的趋势。
The microstructure and hardness evolution of 12CrlMoV water-wall tubes after failure was analyzed by advanced analysis-test means in order to find the failure reasons. The results show that the failure reason of 12CrlMoV water-wall tube is short-time overheating; the microstructure from back-fire side to face-fire side is F ＋ P, F ＋ S ＋ P, F ＋ B, F ＋ M ＋ T and M ＋ T. The hardness from back-fire side to face-fire side increases.
