高温碱液浓度与温度及应变速率对316L不锈钢应力腐蚀开裂的影响
Influences of Concentration,Temperature and Strain Rate on Stress Corrosion Cracking of 316L Stainless Steel in Alkali Solution at High Temperature
摘 要
通过不同应变速率的拉伸试验,研究了316L不锈钢在不同温度和浓度的NaOH溶液中的应力腐蚀开裂行为,分析了以上三个因素对该钢应力腐蚀开裂的影响.结果表明:当应变速率为10-5 s-1时,316L不锈钢不会发生明显的应力腐蚀开裂,而当应变速率降低到10-6 s-1时,在高温低浓度的NaOH溶液中该钢会发生明显的应力腐蚀开裂;当应变速率为10-6 s-1时,NaOH溶液温度对316L不锈钢应力腐蚀开裂的影响程度要高于浓度的.

Abstract
Stress corrosion cracking (SCC) behavior of 316L stainless steel in NaOH solutions with different concentrations was investigated by using tension test at different strain rates and temperatures.And the effects of above three factors on stress corrosion cracking were analyzed.The results show that at the strain rate of 10-5 s-1,SCC of 316L stainless steel was not obvious,while the strain rate decreased to 10-6 s-1,SCC of 316L stainless steel in alkali solution at high temperature was remarkable.Effect of temperature of NaOH solution on SCC of 316L steel was more remarkable than solution concentration at 10-6 s-1.
