The effect of heat treatment and alloying elements of copper and tin on the microstructure and mechanical properties of austempered ductile cast iron alloys is investigated. The austenitizing temperature of 890°C, the isothermal transformation (austempering) temperatures of 285, 335 and 375°C, and austempering times of 15, 30, 75 and 150 minutes are studied. The alloying elements of copper and ...

Among the various causes of free chlorine consumption in drinking water distribution networks, the internal corrosion of pipes has not been so far seriously considered. This work focused on the corrosion study of cast iron, as a representative material of those networks, in non-chlorinated and chlorinated waters, by both electrochemical impedance spectroscopy and classical photographic observat...

In this work, the results obtained from studying the corrosion of cast iron in freely aerated stagnant Arabian Gulf seawater (AGS) at room temperature were reported. The study was carried out using weight-loss (WL), cyclic potentiodynamic polarization (CPP), open-circuit potential (OCP), and electrochemical impedance spectroscopy (EIS) measurements and complemented by scanning electron microsco...
