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...
متن کاملMicrostructure analysis of AZ31 magnesium alloy welds using phase-field models
We use phase-field models to characterize the microstructure present in magnesium AZ31 alloy solidified under welding conditions. We focus our attention on the study of the conditions under which a columnar-to-equiaxed transition (CET) is observed in resistance spot welds. Our simulations show how the size and shape of the columnar and equiaxed regions depend on factors such as cooling rate, te...
متن کاملEffect of Temperature on Diffusion-Bonded Joint of AZ31 Magnesium and 7075 Aluminum Alloy
In this study, the effect of temperature on the diffusion welding of AZ31 magnesium alloy and 7075 aluminum was discussed. Diffusion welding temperature was the most important parameter since all mechanisms are sensitive to temperature in Diffusion welding method. Intrusive contacts between the two alloys at temperatures of 430, and 440 °C 450 and took 60 min. In all tests constant pressure and...

متن کاملCorrosion behaviour of AZ31 magnesium alloy with different grain sizes in simulated biological fluids.
The corrosion behaviour of AZ31 magnesium alloy with different grain sizes immersed in simulated body fluids was compared in chloride solution (8 gl(-1)) and in phosphate-buffer solution (PBS). The influence of immersion time was also analyzed. Electrochemical techniques such as open circuit potential, polarization curves, transient currents and electrochemical impedance spectroscopy, complemen...
