合金的拉伸性能通常是在室温和大气下以中等e(应变速率)来测定。但是,试验条件是涉及T(试验温度)、t(试验时间)、E(介质)的,与合金性能有关的任意试验参数。由于多种原因,故研究T、e、E对拉伸性能的影响就显得很重要,因这些与合金的质量控制和技术条件以及工艺成形(如超塑性加工成形)有联系。用于测定SCC(应力腐蚀开裂)敏感性的恒e法的研究便属于这一范畴。大量试
The tensile properties of alloys are usually measured at moderate e (strain rate) at room temperature and in the atmosphere. However, the test conditions are any of the test parameters related to the properties of the alloy, involving T (test temperature), t (test time), E (medium). For a variety of reasons, it is important to study the effects of T, E, E on the tensile properties as these relate to the quality control and technical conditions of the alloy and to the forming of the process such as superplastic forming. The study of the constant e method used to determine the sensitivity of SCC (Stress Corrosion Cracking) falls within this category. A large number of tests
