本文研究温度对16MnRE钢在H_2S饱和水溶液中疲劳扩展速率的影响,是前文的继续。进一步检验以前所得的结果在不同温度下是否仍然正确;并测定腐蚀疲劳裂纹扩展的激活能,了解H_2S饱和水溶液腐蚀环境对16MnRE钢疲劳裂纹扩展影响的实质。一、实验方法16MARE钢热轧后,试验前未经热处理。其化学成分(wt-%)为
This article studies the effect of temperature on the fatigue expansion rate of 16MnRE steel in H 2 S saturated aqueous solution, which is the continuation of the previous article. Further test whether the results obtained before are still correct at different temperatures; and determine the activation energy of corrosion fatigue crack growth to understand the corrosive environment of H 2 S saturated aqueous solution on fatigue crack growth of 16MnRE steel. First, the experimental method 16MARE steel after hot rolling, before the test without heat treatment. Its chemical composition (wt-%) is
