Constitutive Models for AZ31 Magnesium Alloys

Key Engineering Materials, 2008
The present investigation aims at studying and modelling the flow behaviour of the AZ31 magnesium alloy by means of torsion tests performed in extended ranges of temperature and strain rates. Two types of rheological models were considered. The former is based on the power law equation, whilst the latter is based on the Sellars and Tegart approach. The

Microwave-assisted magnesium phosphate coating on the AZ31 magnesium alloy

Biomedical Materials, 2017
Due to the combination of many unique properties, magnesium alloys have been widely recognized as suitable metallic materials for fabricating degradable biomedical implants. However, the extremely high degradation kinetics of magnesium alloys in the physiological environment have hindered their clinical applications.

The Press Formability in Magnesium Alloy AZ31

Materials Science Forum, 2000
Formability on cylindrical deep drawing and mechanical properties at relatively low temperature was investigated for a commercially rolled AZ31 magnesium. A small punch radius, which ratio to thickness was 2.5, was adoped intentionally. At room temperature, brittle fracture occurred near the flat portion of punch shoulder like as blanking. The ratio of

Citrate Gel Conversion Coating on AZ31 Magnesium Alloys

ECS Transactions, 2013
A 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

Ellipsometric Characterization of AZ31 Magnesium Alloy

Materials Science Forum, 2018
Ellipsometry 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, 2007
Abstract 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.

Modelling dynamic recrystallisation in magnesium alloy AZ31

International Journal of Plasticity, 2021
Abstract In this paper, a dynamic recrystallisation (DRX) viscoplastic self-consistent (VPSC) model is created to predict the continuous DRX (CDRX) and twin-assisted DRX (TDRX) behaviour within an AZ31 magnesium (Mg) alloy over temperatures ranging from 25 °C to 200 °C.

Tailoring biodegration rate of AZ31 magnesium alloy

Electrochimica Acta, 2022
The biocorrosion phenomenon is an important mechanism that determines the biodegradability capacity. The effectiveness of studies on biodegradable materials is directly proportional to detailed corrosion experiments and analysis of formation mechanisms. In this context, experiments and analyzes have also become frequently used for magnesium alloys.

Ion Implanted AZ31 Magnesium Alloy

Materials Science Forum, 2007
Ion 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.
