Materials Science and Technology
Heterostructured materials have recently attracted extensive attentions from the materials community due to their superior combination of strength and ductility as compared to the conventional homogeneous counterparts. In the present study, the laminate AZ31/WE94/AZ31 Mg alloy was produced by vacuum diffusion bonding. The post annealing was carried out

High temperature oxidation of AZ31+0.3wt.%Ca and AZ31+0.3wt.%CaO magnesium alloys
Corrosion Science, 2013Abstract Magnesium alloys of AZ31 + 0.3 wt.%Ca and AZ31 + 0.3 wt.%CaO were cast and oxidized between 450 and 650 °C in atmospheric air. The initially added Ca and CaO enabled to cast the alloys in air without using environmentally hazardous SF6 gas, by forming a thin CaO-rich barrier layer at the surface during casting.

The Press Formability in Magnesium Alloy AZ31
Materials Science Forum, 2000Formability 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

Damping in AZ31 ECAP-Processed Alloy
Solid State Phenomena, 2008Study of anelasticity in AZ31 magnesium-based alloy in initial (hot-rolled at 370 оС) condition and after one and four passes of equal channel angular pressing is carried out. An internal friction peak was found at 170 °C at a frequency f of about 1 Hz.

Temperature Influences on Springback of AZ31 Sheet
Advanced Materials Research, 2010Researches on bending property of the AZ31B magnesium alloy sheet have been focusing on the loading methods and their own performance, while the temperature is less concerned in the past. In this paper, the law of the springback with the temperature changing was especially studied.

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.

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
