This short communication investigate the relationship of mechanical properties and stress corrosion cracking (SCC) behavior of microstructures in a heat-affected zone of high strength low-alloy steel in artificial seawater. It showed that SCC susceptibilities of different microstructure were controlled by electrochemical corrosion behavior and grain size, which is decided by the SCC mechanism.

人工海水中高强钢焊件热影响区显微组织应力腐蚀机理研究

这篇简短的通讯研究了人工海水中高强度低合金钢热影响区微观结构的力学性能和应力腐蚀开裂 (SCC) 行为之间的关系。结果表明，不同微观结构的 SCC 敏感性受电化学腐蚀行为和晶粒尺寸的控制，这由 SCC 机制决定。
