stress corrosion cracking
基本释义
- 应力腐蚀开裂：应力腐蚀开裂（SCC）是在腐蚀环境中裂纹形成的过程。它会导致通常具有延性的金属合金在受到拉应力作用时，尤其是在高温下，出现意外和突然的失效。SCC在化学上具有高度特异性，只有在暴露于少数化学环境时，某些合金才可能发生SCC。对于给定合金引起SCC的化学环境通常只对金属具有轻微的腐蚀作用。因此，严重SCC的金属零件可能看起来明亮而有光泽，但内部却充满了微观裂纹。这一因素使得SCC在失效之前常常难以检测到。SCC通常进展迅速，而且在合金中比纯金属更常见。特定的环境至关重要，只需要极少量的某些高活性化学物质就能引起灾难性的开裂，常常导致毁灭性和意外的失效。
