Two factors that have been found to have an important influence on stresscorrosion crack initiation, in certain cases, are the extent of environmental access and the presence of residual surface stresses. These are discussed, and examples from service are cited where such effects have played a ...
Intergranular stress-corrosion cracking (IGSCC) is a form of environmentally induced crack propagation causing premature failure of elemental metals and alloys. It is believed to require the simultaneous presence of tensile stress and corrosion; however, the exact nature of this synergy has eluded expe...

3.4Stress-corrosion Cracking Initiation of stress-corrosion cracking (SCC) results from the conjoint action of an aggressive environment, a sensitive material, and a static applied load ortensile residual stress(seeStress Corrosion Crackingin Metals,Stress Corrosion Cracking: Mechanisms). It includes crac...
An experimental investigation of stress corrosion cracking in metals is reproted for several alloy-corrodent systems. Internal damping measurements are made on the metals in the as-received condition and after they have been exposed to a corrosive environment. Data curves are reported for different ...

The problem of stress corrosion cracking (SCC), which causes sudden failure of metals and other materials subjected to stress in corrosive environment(s), has a significant impact on a number of sectors including the oil and gas industries and nuclear power production. Stress corrosion cracking rev...
In order to improve the stress corrosion cracking resistance of the weldable Al-Zn-Mg alloys with medium strength, the near-solvus pre-precipitation follow... 李松,陈康华,刘红卫,... - 《Transactions of Nonferrous Metals Society of China》 被引量: 68发表: 2003年 Stress corrosion cracking susce...
Stress corrosion (SCC) falures in AlZnMg alloys show ideal brittle fracture in the grain boundaries. In sensitive alloys an increased tendency to intercrystalline rupture was also observed in the tensile test in the absence of a corrosive medium. A model was developed according to which the fai...
It is necessary to determine whether Stress Corrosion Cracking (SSC) can occur under compressive stress in stress corrosion environments in which crack propagation occurs by dissolution at an essentially film-free crack tip. It has been noted that the SCC mechanism of mild steels in nitrate solution...
