. Therefore, when Zr-1Nb alloy is corroded in LiOH aqueous sol ution, a soluble niobate produced by the reaction between the corrosion products of β-Nb particles and LiOH results in the formation of pores......
Influence of yield-to-tensile strength ratio (Y/T) on failure assessment of defect-free and corroded X70 steel pipelineZHANG Shun-hu(章顺虎)1, 2, ZHAO De-wen(赵德文)1, WANG Xiao-nan(王晓南)2(1. State Key... corrosion defects is a function of the Y/T, pipe geometry t0/D0 and engineering tensile strength, and increases as Y/T or t0/D0 increases; whilst the burst pressure of corroded X70 pipe decreases......
Corrosion products of reverse crevice corrosion of copperLin Lu and Xiao-gang Li School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing 100083, China摘 要... products. With the aid of these techniques, the existence of reverse-crevice corrosion in copper was verified, i.e., while the surface of a crevice was corrosion free, the outside surface of the copper......
