在各种载荷条件下?尤其是施加不同时间的少量脉动应力条件下,研究了暴露于碳酸盐—亚碳酸盐溶液中的管线用钢的应力腐蚀开裂行为。结果表明,应力腐蚀裂纹的聚结在整个裂纹扩展过程中起关键作用,因
The stress corrosion cracking behavior of pipeline steel exposed to carbonate-bicarbonate solution was investigated under various loading conditions, especially at a small amount of pulsating stress applied at different times. The results show that the coalescence of stress corrosion cracking plays a key role in the entire crack propagation process because
