一金属应力腐蚀开裂问题的严重性金属在静拉应力和特定腐蚀环境共同作用下发生的脆性断裂称为应力腐蚀开裂(以下用SCC表示)。随着工业的发展,以及应用合金种类的增多,SCC事故也与日俱增。从早期的军事工业中发现黄铜弹壳的“季裂”问题出现以来,又有许多部门发生其他金属的SCC问题:交通运输中蒸汽机车铆接锅炉用碳钢的碱脆,化工、石油和造纸工业中不锈钢的SCC,
Severity of a Metal Stress Corrosion Cracking Problem A brittle fracture of a metal that occurs under a combination of static tensile stress and a specific corrosive environment is called stress corrosion cracking (hereinafter referred to as SCC). With the development of industry, and the increase of application types of alloy, SCC accidents are also increasing day by day. Since the advent of the “seasonal crack” of brass casings in the early military industry, SCM problems of many other metals have occurred in many sectors: transportation of steam locomotive riveting boilers with carbonaceous alkaline, chemical, petroleum and Stainless steel SCC in the paper industry,
