| 摘 要： | 时效前对Ａｌ－Ｌｉ－Ｃｕ－Ｍｇ－Ｚｒ（２０９１）合金进行冷轧和温轧关系，用慢应变速率拉伸试验研究了合金在３．５％ＮａＣｌ溶液中的应力腐蚀敏感生。结果表明，预轧制变形提高了合金的应力腐蚀抗力。冷轧受形量为２０％以及温轧温度为１８０℃时，合金都具有最低的应力腐蚀敏感性。对合金应力腐蚀抗力与显微组织的关系进行了探讨。

| Abstract: | Stress corrosion cracking(SCC) susceptibility of (2091) Al-Li alloy in 3. 5% NaCl solution was studied by slow strain rate tensile est, under cold-rolling or warmrolling reduction prior to aging. Results have shown that rolling deformation prior to aging improve SCC resistance. Under cold-rolling (20% reduction) or warm-rolling at 180C, the SCC susceptibility of the alloy is the lowest. The correlation betweem SCC resistance and microstructure of the alloy was investigated. |
