Anodizing of Magnesium Alloy Az31 by Alkaline Solution

-Anodizing of AZ 31 Mg alloy was investigate in 3M KOH solution for 10, 20 and 30min. at constant voltage of 5V. Atomic force microscope (AFM) used to investigate the roughness of anodic film formed on the surface while the scanning electron microscope (SEM) was used to determine the morphology of the anodic film, it was found that the roughness of the anodic film is mainly depend on the anodiz...

Strain-induced Texture Development in the Magnesium Alloy Az31

Magnesium alloys are receiving increasing attention as a structural material in vehicles to reduce weight and increase fuel economy. Understanding the formability of lightweight alloys is one key to their successful introduction in vehicles. We present results of X-Ray diffraction and electron back-scatter diffraction texture measurements in as-cast and uniaxially compressed AZ31 for a variety ...

Towards Superplastic Forming of Az31 Magnesium Alloy with Controlled Microstructure

A recent study on post-superplastic forming properties has shown that heating time prior to testing has a major effect on the post-forming properties of superplastically-formed AZ31 Magnesium alloy sheets. To this point, there has been very little examination into the effects of pre-heating or annealing on superplastic forming. In this work, these effects are examined using AZ31 Mg alloy sample...
