| 摘 要： | 采用慢应变速率实验研究了钛合金TA7在醇类溶液等介质中的应力腐蚀敏感性，结果表明：钛合金TA7在醇类溶液中有明显的应力腐蚀敏感性；在含有Cl^-离子的醇类溶液中有强烈的应力腐蚀敏感性；钛合金的应力腐蚀开裂通常源自点蚀孔底部。 |
| 关 键 词： | 钛合金 TA7 醇溶液 敏感性 应力腐蚀 慢应变速率实验 点腐蚀 腐蚀裂纹 |

| Abstract: | The stress corrosion susceptibility of the titanium alloy TA7 in various alcohol solutions and the Cl-ion effect were investigated by using the SSRT testing method, SEM analysis and metallographic examination. The results show that the titanium alloy exhibits obvious susceptibility to SCC in ethyl alcohol and methyl alcohol and but more striking susceptibility to SCC in 0.6%HCl-methyl alcohol. SCC cracks of the titanium alloy in these solutions initiated in general from the bottom of pits. |
| Keywords: | SCC susceptibility alcohols solution titanium alloy SSRT test pitting corrosion |
