- 摘要:
- 针对 ZGH3030 合金重熔浇铸力学试棒在 800 ℃拉伸试验过程中拉伸强度低于标准值的现象，本实验采用
型号为 WDW-100 试验机， 对不同力学试棒通过设定不同的横梁位移速率和相同试棒拉伸过程中改变横梁位移速率，
研究了横梁移动速率对 ZGH3030 合金强度的影响。 结果表明，ZGH3030 合金在 800 ℃拉伸试验过程中，改变横梁位移
测试条件，能够改变合金的抗拉强度值。 因此，该方面的研究，有助于在以后类似铸造高温合金拉伸过程中，通过合理设
定横梁位移速率，获得合适的抗拉强度值。
Aiming at the phenomenon that the tensile strength of the remelted casting ZGH3030 alloy is lower than the standard value during the tensile test at 800 ℃, the WDW-100 testing machine was used in this test to study the influence of the beam displacement rate on the strength by setting different beam displacement rates for different mechanical test bars and changing the beam displacement rate of the same test bar during the test. The results show that the tensile strength of the ZGH3030 alloy can be changed by changing the beam displacement test conditions during the tensile test at 800 ℃. Therefore, the appropriate tensile strength can be obtained by reasonably setting the displacement rate of the beam, which is helpful for the tensile test of similar cast superalloys in the future.
