| 摘 要： | 本文对ZCE36Z35钢在3.5%Nacl 和10%NH_4NO_3水溶液中的疲劳裂纹扩展速率(FCGR)及外加极化电位的影响进行了实验研究,结合应力腐蚀(SCC)实验,作者认为,除非在阴极极化条件下出现强烈充氢情况,该钢在中性水溶液中的麦劳裂纹扩展主要受氧去极化作用(ODR)控制而不是氢脆(HE)机制.

| Abstract: | In this paper,fatigue crack growth rates(FCGR)for the ZCE_(36)Z_(35)steel in 3.5%NaCl and 10% NH_4NO_3 solutions are studied by means oftests,and the effect of applied polarization potentials is also discussed.In combination with the results of stress corrosion cracking(SCC)tests,it is proposed that fatiguecrack growth for this steel in foregoing aqueoussolutions is controlled mainly by oxygen de-polarization reactions(ODR)rather than by hydrogen embrittlement(HE)mechanism unless cathodicpolarization results in drastic hydrogen charging. |
