Forming Limit Curves

The formability of AZ31 magnesium alloy sheets has been investigated in the temperature range varying from 200 to 300°C. Forming limit diagrams have been obtained by performing Nakazima-based tests. The different straining conditions have been investigated using sheet blanks with several length to width ratios. The forming limit curves have been related to the microstructural evolution occurring during deformation. The forming limit diagrams have shown a remarkable increase in formability with temperature that could be related to the occurrence of full dynamic recrystallization at 300°C.

The aim of this work is to discuss the corrosion characteristics of plasma electrolytic oxidation (PEO) films formed on AZ31 magnesium alloys in alkaline silicate solution. The uniform and pitting corrosion resistance of the PEO films was investigated by potentiodynamic polarization tests and potentiodynamic scanning curve tests. The composition, the structure and the element contents of the films after immersed in 3.5 wt.% NaCl solution for different time were investigated by XRD、SEM and EDS. The results indicated that the corrosion occurred on AZ31 magnesium alloy and treated PEO samples during five days immersion, but the corrosion tendency of the PEO treated samples is smaller than that of AZ31 magnesium alloy.
