以X-70管线钢近中性pH值溶液(NS4和实际土壤溶液)为研究对象,研究了恒载荷、慢应变速率拉伸(SSRT)和循环载荷等不同条件下的环境开裂行为.结果表明,在该体系中局部应变速率是联系各种不同断裂过程的纽带,决定着断裂的模式.当该局部应变速率低于发生应力腐蚀开裂(SCC)敏感局部应变速率的上限(即5×10-5 s-1)时,SCC才能够发生;在循环载荷作用下,当该局部应变速率高于此上限时,将发生力学因素起主导作用的腐蚀疲劳(CF)开裂;该局部应变速率继续升高时,将发生机械断裂.对X-70管线钢在近中性pH值的环境开裂,不论开裂过程是溶解或(和)氢的作用占主导,均受局部应变速率控制.在通常遇到的现场服役条件下,X-70管线钢在近中性pH值溶液中的开裂模式是SCC,不是CF,应称之为"近中性pH值应变促进腐蚀开裂",实质上这是一种由局部应变速率决定的环境开裂行为.
