A study on the stress corrosion mechanism of microstructures in a heat-affected zone of high-strength steel weldment in artificial seawater

Abstract

This short communication investigate the relationship of mechanical properties and stress corrosion cracking (SCC) behavior of microstructures in a heat-affected zone of high strength low-alloy steel in artificial seawater. It showed that SCC susceptibilities of different microstructure were controlled by electrochemical corrosion behavior and grain size, which is decided by the SCC mechanism.

Numerical analysis of the phased array imaging with a stacked plate buffer

“…Therefore, stress corrosion cracking and fatigue cracking are likely to occur in the heat-affected zone, which is the most important area for the maintenance of piping. [1][2][3][4][5][6][7][8][9][10] Especially in nuclear power plants, accurate sizing of cracks in the heat-affected zone is of great interest because it enables accurate decision of pipe-replacement schedule, resulting in reducing radioactive waste and ensuring the integrity of the plant at the same time. [11][12][13] Imaging techniques using phased-array (PA) ultrasonic have been used for crack sizing in the heat-affected zone.…”

Improvement of corrosion resistance of galvanization/nickel/chrome plating low carbon steels in H2SO4under dynamic condition

“…Coatings dependent on metals, polymers, and different epoxies have been created notwithstanding as of now delivered business items. Some recent researches [26][27][28][29][30][31][32][33][34][35][36] have been done for considering the different operating and processing parameters and their effects on corrosion for better understanding the corrosion mechanism in relation to industrial perspectives.…”
