本文简明扼要地阐述了金属材料在许多环境中同时受应力和腐蚀的作用,产生了裂纹甚至断裂;分析了应力腐蚀产生的机理,介绍了低碳钢和奥氏体不锈钢产生应力腐蚀的原因、现象和影响因素;同时,也提出了防止应力腐蚀裂纹产生的四种方法。
This paper briefly states that metal materials are subject to stress and corrosion in many environments at the same time, causing cracks and even fractures. The mechanism of stress corrosion is analyzed. The causes of stress corrosion in mild steel and austenitic stainless steel are introduced. Phenomenon and influence factor; At the same time, also put forward to prevent stress corrosion cracking of the four methods.
