Abstract
In this study, in the range of 0.2% to 1.0% Ce elements were added to AZ31-1Ca alloys produced by low pressure die casting method. Hot rolling process was applied to these produced alloys at 400 °C with 1,5 m/min rolling speed at 15% deformation rate per pass. The corrosion resistance of samples extracted from sheets that have included different twins fraction after various Ce adding were investigated at 3.5% NaCl solution for 72 hours according to ASTM G31 of Standard Practice for Laboratory Immersion Corrosion Testing of Metals. The effect of secondary phases, grain size and twins on immersion corrosion resistance of investigated alloys was studied systemically on the base of microstructure analysis.
