Abstract
Variations in the transpassive potential (Et) and open circuit potential (OCP) of Alloy 825 were investigated at high-temperature pressurized water–Cl solutions. Using an experimental design strate...

Abstract This work addressed the microstructure-corrosion behavior relationship of Inconel 617/AISI 310 dissimilar electron beam welds. The obtained results showed that the weld metals had weaker general corrosion resistance and pitting corrosion behavior than parent metals, as a result of the segregation of the elements and formation of the precipitates which were rich in Mo, Nb, Cr and Co. With increasing the welding travel speed, a finer dendritic microstructure was observed in weld metal, le...
