一、前言近十年来,慢应变速率技术(SSRT)因其显著的优点已广泛应用于测试应力腐蚀开裂(SCC)的敏感性。然而,对于这种动态试验,如何分析不同应变速率的实验结果是一个值得探索的问题。正确的分析还有助于对开裂机理的深入认识。例如,合适的应变速率是揭示某些金属/介质体系SCC敏感性的关键;过快或过慢的应变速 I. INTRODUCTION Slow strain rate technology (SSRT) has been widely used to test the sensitivity of stress corrosion cracking (SCC) due to its significant advantages over the last decade. However, how to analyze the experimental results of different strain rates is a problem worth exploring for this kind of dynamic test. Correct analysis also helps to gain insight into the mechanism of cracking. For example, a suitable strain rate is the key to revealing the sensitivity of some metals / media systems to SCC; too fast or too slow strain rates
