摘要
应力腐蚀是压力容器腐蚀破坏的重要形式,尤其是这种断裂失效呈脆性断裂的特点,易导致灾难性后果。阐述了压力容器应力腐蚀断裂产生的条件和特征,并从合理选材、降低或消除应力和改善环境等方面提出了控制应力腐蚀断裂的技术措施。
The stress corrosion wa s one of lim iting factors in the lifetime of pressur e vessels.The stress corrosion lead to e mbrittlement cracking and destroy the pr essure vessels.The formation conditions and character of stress corrosion fractu re for pressure vessels was summarized.S o me measures were proposed to prevent or c ontrol stress corrosion by selecting mat erials,decreasing and eliminating stress ,and or altering condition of pressure v essels used.
