constant load tensile test was adopted to study the influence of welding material match and alloy element content on sscc(sulfide stress corrosion cracking) of domestic pipeline steels.
结果表明:焊接匹配、合金元素是影响国产管线钢sscc的重要因素。
by constant load tensile test and fracture analysis, scc of ly6 aluminum alloy is owing to the anodic dissolution effect.
