摘要
GB/T 228.1-2010实施以来关于拉伸试验速率控制方式和试验速率的选择存在很多分歧。本文研究了不同试验控制方式和试验速率对Ti6Al4V合金拉伸试验结果的影响,试验结果表明对于钛合金材料采用横梁位移换算后的位移速率获得的屈服强度结果与相应的应变速率控制测试结果基本相同,而采用黑色金属推荐的5%Lcmin-1速率获得的屈服强度明显偏高,对于Ti6Al4V合金试验过程中不需要对试验速率进行刚度修正。
Since the implementation of GB/T 228.1-2010, there have been many divergences in the choice of the rate control method and the rate of tensile test. In this paper, the effects of different test control methods and test rates on the tensile test results of Ti6Al4V alloy are studied. The results show that the yielding strength of Ti6Al4V alloy obtained by using the displacement rate converted from the transverse beam displacement is basically the same as that obtained by the corresponding strain rate control test, and the yield strength of Ti6Al4V alloy is deduced by using ferrous metal. The yield strength of Ti6Al4V alloy at the recommended 5%Lcmin-1 rate is obviously higher than that at the recommended 5%Lcmin-1 rate.
