摘要
采用阴极渗氢和低应变速率拉伸等试验，研究了氢对不同时效状态７１７５铝合金力学性能的影响．结果表明，屈服应力、断裂强度及延伸率等均随充氢时间的延长而下降；且在相同充氢时间条件下。
Effects of hydrogen on the mechanics of different aged state 7175 aluminium alloy have been in vestigated by means of cathodic H permeation,slow strain rate tension and so on. The results indicate that yield stress,fracture strength as well as elongation decrease as aging time increases and the degree of reduction decreases as aging time increases at the same hydrogen charging time.
