摘要

对4340钢在含氧或含氯水溶液中的应力腐蚀开裂行为进行了研究,拉伸实验结果表明,在100°C的脱氧蒸馏水中,4340钢的断裂主要属于韧性断裂,氧或氯的加入会增加4340钢的SCC倾向,使断裂机制由韧性断裂转变为脆性断裂。氧或氯化物的存在会使4340钢在100℃水溶液中的sccc略有降低,氧和氯化物同时存在,同时作用会进一步增加4340钢在水溶液中的sccc倾向。

Corrosion Failure of AISI4340 Steel in Oxygen-Containing Aqueous Chloride Solution
Stress corrosion cracking behavior of 4340 steel in oxygen-containing or chloride containing aqueous solution was researched, the tensile experiment results indicated 100°C deaerated distilled water, the rupture of 4340 steel mainly belongs to ductile fracture, the addition of oxygen or chloride would increase the SCC tendency of 4340 steel and transformed the rupture mechanism from ductile fracture to brittle rupture, the existence of oxygen or chloride would decreaseKISCCof 4340 steel in 100°C aqueous solution slightly, the simultaneous action of oxygen and chloride existed, and the simultaneous action would further increase the SCC tendency of 4340 steel in aqueous solution.
