溶解氧和溫度對06Cr17Ni12Mo2Ti不銹鋼在超臨界水中應力腐蝕的影響

Effects of dissolved oxygen and temperature on the stress corrosion of 06Cr17Ni12Mo2Ti stainless steel in supercritical water

  • 摘要: 通過慢應變速率拉伸試驗,在超臨界水環境中研究了溶解氧和溫度對06Cr17Ni12Mo2Ti不銹鋼的應力腐蝕開裂傾向的影響規律.試驗結果表明:在含不同溶解氧量(0/200/2000μg·kg-1)的450℃和550℃超臨界水環境中,不銹鋼都呈現出不同程度的應力腐蝕開裂傾向.隨著水中溶解氧含量的增加,不銹鋼的應力腐蝕開裂傾向更為明顯.隨著溫度的上升,應力腐蝕開裂傾向反而會下降.在含不同溶解氧量(0/200/2000μg·kg-1)的650℃超臨界水環境中,不銹鋼只發生塑性斷裂,未發現應力腐蝕開裂傾向,并且溶解氧對其影響也不是很明顯.

     

    Abstract: The effects of dissolved oxygen(DO) and temperature on the stress corrosion cracking(SCC) of 06Cr17Ni12Mo2 Ti stainless steel(SS) in supercritical water environments were investigated by slow strain rate tensile tests(SSRT). It is found that the SCC susceptibility of the stainless steel is observed in 450℃ and 550℃ supercritical water environments containing different amounts of dissolved oxygen(0/200/2000 μg·kg-1). The effect of dissolved oxygen on the SCC susceptibility is more remarkable with increasing amount of dissolved oxygen. However,the SCC susceptibility decreases with the increase of temperature. In 650℃ supercritical water environments containing different amounts of dissolved oxygen(0/200/2000 μg·kg-1),ductile fracture can be found,but the SCC susceptibility is not observed. In these environments,the effect of DO is negligible.
