... array, they allow the corrosion process to propagate deeper into the matrix of the metal. The purpose of heat treatment is to disperse the second phase particles and disrupt the interconnected networks. Previous work has demonstrated that lowering the tin content results in lower corrosion rates...

... testing was conducted in 60-70% sulfuric acid at boiling temperatures. Autoclave testing was performed at the same concentrations of acid, but at temperatures up to 180°C. Updated 5 mpy iso-corrosion curves for zirconium in sulfuric acid are presented. The effect of heat treatment on corrosion resistance...

...-52 grade of steel and the pertinent factors that affect the corrosion rate under different heat treatment conditions in a CO₂ - brine solution has been studied and discussed as a function of temperature and pressure of carbon dioxide. An interface controlled corrosion mechanism has been...
