常见应力腐蚀标准试验方法对比及应用

Comparison and Application of Common Stress Corrosion Standard Test Methods

各种应力腐蚀评价方法的试样形式多样、加载方式各不相同,给从事科研和检测的工作者带来一定的选择困难。通过对恒位移法、恒载荷法和慢应变速率法等几种常见应力腐蚀试验方法进行对比分析,列出了各自的适用范围、评价指标及其优缺点,为科研和检测工作者科学合理地选择评价方法提供参考。

Due to various specimen forms and different loading modes of stress corrosion evaluation methods,it is difficult for researchers and testing workers to make certain choices.Through comparison and analysis of several common stress corrosion test methods,including constant displacement method,constant load method and slow strain rate method,the application range,evaluation index and their advantages and disadvantages were listed.It provided a reference for researchers and testing workers to select the evaluation method scientifically and reasonably.
