    摘要:

    本文通過慢應(yīng)變速率拉伸實驗和動態(tài)電解充氫實驗分別研究了Al-xMg-3.1Zn鋁合金的應(yīng)力腐蝕開裂行為及其氫脆行為。結(jié)合宏觀斷口和微觀斷口形貌分析研究了合金發(fā)生應(yīng)力腐蝕開裂的進程。通過對合金應(yīng)力腐蝕開裂的機制進行分析闡明了合金中Mg元素含量對合金應(yīng)力腐蝕開裂行為的影響。研究結(jié)果表明在該合金體系中存在應(yīng)力腐蝕開裂,且合金的應(yīng)力腐蝕敏感性隨合金中Mg含量的降低而降低;這與合金的陽極溶解行為與氫脆行為隨Mg元素含量降低而減弱有著直接的關(guān)系。在這當中,合金中晶界析出相的數(shù)量隨Mg元素含量降低而減少起到了至關(guān)重要的作用。

    Abstract:

    The stress corrosion cracking and hydrogen embrittlement of the Al-xMg-3.1Zn aluminum alloys were studied by slow strain rate tensile tests and dynamic electrolytic hydrogen charging experiments, respectively. The effect of Mg on the stress corrosion cracking behaviors was indicated combining with transmission electron microscopy and fracture analysis. The results showed that the stress corrosion cracking was happened in the studied alloys, and the corrosion susceptibility decreased with a decrease of Mg content due to the decrease of the grain boundary precipitates continuity. This was result from the decrease in the anodic dissolution of grain boundary precipitates and hydrogen embrittlement behaviors with a decrease of Mg content.
