摘　　要：在海洋工程中,应力腐蚀开裂行为一直是一个亟需解决的问题。在海洋环境中,氯离子被认为是危害最大的阴离子,在氯离子的影响下,不同材料的应力腐蚀特征和机理复杂多变。因此本研究从碳钢、不锈钢、高强钢3种材料的角度探讨了金属材料的应力腐蚀开裂行为,阐述了不同材料在氯离子环境下的应力腐蚀敏感性、应力腐蚀机理及防护手段。Stress corrosion cracking behavior has always been an urgent problem to be solved in offshore engineering.In the marine environment,chloride ion is considered to be the most harmful anion.Under the influence of chloride ion,the stress corrosion characteristics and mechanism of different materials are complicated and varied.In this paper,the stress corrosion cracking behavior of metal materials is studied from the aspects of carbon steel,stainless steel and high strength steel.Meanwhile,the stress corrosion sensitivity,stress corrosion mechanism and control methods of different materials under chloride ion environment are described.
