Citrate Gel Conversion Coating on AZ31 Magnesium Alloys
ECS Transactions, 2013A citrate gel conversion system was developed in this study. The citrate gel, which was obtained by adding ethanol into sodium citrate aqueous solution, was dissolved in glycerin to form the conversion solution. After the consecutive steps of roll coating and heating, a citrate gel conversion coating was made on AZ31 magnesium alloys. Microstructure

Forging of Mg-Alloys AZ31 and AZ80
Materialwissenschaft und Werkstofftechnik, 2005Mg-wrought alloys recently became an engineer material of constantly increasing interest. The mechanical properties of extruded Mg-feedstock of the alloys AZ80 and AZ31 indicate their suitability for automotive applications in form of high-quality forgings. Therefore a detailed knowledge about the forming behaviour is of particular importance. In order

Formability of AZ31 Mg alloy sheets within medium temperatures [PDF]
Journal of Magnesium and Alloys, 2013 The stretching tests of the commercial AZ31 Mg alloy were conducted at 130 °C, 170 °C, 210 °C, at the forming speeds of 10 mm/min and 50 mm/min, respectively. The formability of AZ31 sheets at high temperature was evaluated by forming limit diagrams (FLD)

Fracture micro-mechanisms in hot-rolled AZ31 and AZ31-Sr magnesium alloys
Materials Science and Engineering: A, 2021Abstract Micro specimens of hot-rolled AZ31 and AZ31 + 0.8 wt% Sr magnesium alloys were tensioned in the rolling direction, and fracture micro-mechanisms were studied by in-situ real-time optical observations, electron microscopy, and DIC analysis. In-situ observations indicated that strain localization on the microstructural shear bands developed ...

Ion Implanted AZ31 Magnesium Alloy
Materials Science Forum, 2007Ion implantation was applied to modify the surface properties of magnesium alloy. About 75 keV titanium ions with a dose of 5×1017 ions/ cm-2 and about 35 keV nitrogen ions with a dose of 3×1017 ions/ cm-2 were implanted into AZ31 magnesium alloy, respectively. AFM and FESEM were used to examine the surface morphology of the treated samples.

Ellipsometric Characterization of AZ31 Magnesium Alloy
Materials Science Forum, 2018Ellipsometry is a non-destructive and indirect technique able to characterize both optical and dielectric properties of thin films and bulks, besides determining the thickness of thin films. This characterization is performed by evaluating the change in the polarization state of the incident light when it interacts with the material of interest.

Dynamic recrystallization in AZ31 magnesium alloy
Materials Science and Engineering: A, 2007Abstract The effects of temperature and strain rate, as the most important thermomechanical processing (TMP) parameters, on the microstructural evolution of AZ31 magnesium alloy were studied. This was performed applying hot compression tests at a temperature range of 250–450 °C with various strain rates.

Stress Relaxation in an AZ31 Magnesium Alloy
Key Engineering Materials, 2011Stress relaxation tests have been used in order to determine parameters of a possible thermally activated process in AZ31 magnesium alloy. The samples were deformed at a constant initial strain rate of 6.7x10-5 s-1 at various temperatures between room temperature and 300 °C. Stress relaxation, i.e.

Warm Forging Characteristics of AZ31 Alloy
Advanced Materials Research, 2007Industrial application of magnesium alloys has increased significantly recently. However, wrought magnesium alloys still have a lot of technical challenges to be solved for more applications. First of all, low formability of wrought alloys should be improved by optimizing the processing variables.
