...Yanyan Li; Yuheng Li; Bo Zhang; Zijing Yang; Tianting Chen; Yuchen Wang; Dong Liang; Leimin Deng; Xinxin Zhang Purpose The sensitization issue of AA5083 alloy and thus resulting intergranular corrosion ( IGC ) issue always restrict its wide application in the marine and transportation fields...

... on the SS surface and leads to severe intergranular corrosion. With prolonged tempering time, the susceptibility to intergranular corrosion increases. After heat treatment, the proportion of low-angle grain boundaries (LAGBs) and geometrically necessary dislocation (GND) density decreases, affecting...

...Cong Zhu; Ye Wang; Xingwang Du; Zhixiu Wang; Hai Li Purpose This paper aims to study the effect of aging treatment on tensile properties and intergranular corrosion (IGC) of spray-formed 7055 Al alloy. Design/methodology/approach This study involved tensile test and IGC test, along...

... Na₂S₂O₃ solutions, MF inhibited intergranular corrosion (IGC) because it increased the defects in the oxide film and facilitated the uniform adsorption of low concentration of S on these defects due to its stirring effects, which resulted in a weakened adsorption of S at the grain boundaries. Conversely...

...Xiangyu Wang; Pei He; Qinglong Zhou; Qingyuan Zhou; Manlang Cheng; Yangting Sun; Yiming Jiang; Laizhu Jiang; Jin Li Purpose The purpose of this study is to investigate the intergranular corrosion (IGC) susceptibility of a nitrogen-containing austenitic stainless steel QN2109. The intergranular...

... stages: coating failure, pitting corrosion and intergranular corrosion (IGC). Findings In the first stage, the chromate coating degraded gradually due to the combined action of chloride anions and water molecules, resulting in the complete exposure of AA2024 substrate to 3.5 per cent NaCl solution...

...Jacek Ryl; Anna Arutunow; Mateusz T. Tobiszewski; Joanna Wysocka Purpose – The purpose of this paper is to present a case study of unexpected sensitization to intergranular corrosion of highly resistant AISI 321 steel in petrochemical conditions, where it was subjected to the simultaneous...

... intergranular corrosion process. Design/methodology/approach The investigations were carried out by means of dynamic electrochemical impedance spectroscopy (DEIS). DEIS measurements were conducted “on‐line” while the samples were polarized in agreement with a measurement procedure presented in the ASTM G108...

...Fuad M. Khoshnaw; Ramadhan H. Gardi Purpose Two types of aluminium alloys, 2024‐T3 and 7075‐T6, having been selected, this study aims to investigate the effect of metallurgical aspects on intergranular corrosion. Design/methodology/approach To determine and evaluate the metallurgical effects...
