additions on mechanical and stress corrosion cracking properties of Al-Zn-Mg-Cu-Zr aluminium alloy were investigated by microscopy, hardness, tensile test and stress corrosion cracking test..., hardness, stress corrosion cracking resistance of the Cr and Nb containing alloys are moderately improved, comparing with the alloys without Cr and Nb additions. By Cr and Nb additions the critical......
factors are important contributors to stress corrosion cracking. Key words: anchor bolts; hydrogeochemical modelling; rock bolts and cable bolts; stress corrosion cracking; water chemistry analysis... suffering from premature failures [4-6]. Increasing interest has been shown in identifying these premature failures by considering stress corrosion cracking (SCC) mechanism [4, 7-13], which has also......

Corrosion behavior of 2195 and 1420 Al-Li alloys in neutral 3.5% NaCl solution under tensile stress LI Jin-feng(李劲风), CHEN Wen-jing(陈文敬), ZHAO Xu-shan(赵旭山), REN Wen-da(任文达) , ZHENG Zi-qiao(郑子樵... on the unstressed 2195 alloy. As stress is applied to 1420 alloy, the pit becomes denser and its size is decreased. While, for the stressed 2195 alloy, intergranular corrosion is greatly aggravated and severe......
Introduction Corrosion can range from highly uniform to local extremely during pitting and stress corrosion cracking. In general, corrosion morphologies are rarely uniform. Pits observed on corroded surfaces... An evaluation analysis method for corrosion morphology characterization based on Gaussian filter ZHANG Peng (张 鹏)1, GUO Bin (郭 斌)2, CHENG Shu-kang (程树康)3 1.
