Hot Rolling of AZ31 Magnesium Alloy to Sheet Gauge

SAE Technical Paper Series, 2006
<div class="htmlview paragraph">This study details preliminary results of hot rolling trials of AZ31 alloy sheet using a pilot-scale rolling mill. The aim is to design and optimize the hot rolling schedule for AZ31 in order to produce sheet with a fine and homogeneous microstructure.

An Investigation of TIG Welding of AZ31 Magnesium Alloy Sheets*

Materials Testing, 2014
Abstract In this study, butt welding of commercial AZ31 magnesium alloy sheets has been investigated by using the tungsten inert gas welding process with alternating and pulsed current. Magnesium alloy welding, although well developed and understood, can present some problems, such as porosity, hot cracking, oxide formation, etc. Samples

Deformation Mechanisms of AZ31 Magnesium alloy

2016
A detailed investigation of the deformation mechanisms plays an important role for a better understanding of texture evolution and anisotropic behavior of magnesium wrought alloys. Therefore, room temperature deformation tests of AZ31 hot rolled sheets and extruded bars have been performed.

Numerical-Experimental Characterization of a Superplastic AZ31 Magnesium Alloy

Materials Science Forum, 2007
In this work the superplastic behaviour of a hot rolled AZ31 magnesium alloy sheet under a biaxial tension test with the blow forming technique is presented and reported. The specimen dome height and its thickness distribution, during and after the test, have been used as characterizing parameters. A numerical FE model of the test has been developed in

The Effect of Manganese on the Grain Size of Commercial AZ31 Alloy

Materials Science Forum, 2005
The effect of manganese on grain refinement of a commercial AZ31 alloy has been investigated using an Al-60%Mn master alloy splatter as an alloying additive at 730 °C in aluminium titanite crucibles. It is shown that grain refinement by manganese is readily achievable in AZ31.

Microstructures and Properties of Laser Al Alloying on AZ31 Magnesium Alloy

Advanced Materials Research, 2011
In order to improve corrosion and wear resistance of magnesium alloy, Al coating was prepared on the AZ31 magnesium alloy by the thermal spraying, then the Al-rich layer was obtained by using a CO2 laser re-melting. The microstructures and phases of the alloying layer were analyzed by canning electron microscope (SEM) and X-ray diffraction apparatus ...

Tube extrusion of AZ31 alloy with Sr additions

Materials Science and Engineering: A, 2012
Abstract Three Mg alloys (AZ31, and AZ31 + 0.4 and 0.8 wt%Sr) were successfully hot extruded into tubes at 400 °C through a porthole die. Strontium (Sr) additions to AZ31 alloy reduced twining and the dynamically recrystallized grain size. However, Sr also increased the surface cracking tendency during extrusion.

Strain-hardening behaviour of AZ31 magnesium alloys

International Journal of Materials Research, 2009
Abstract The in-plane tensile behaviour of rolled sheets of the magnesium alloy AZ31 was investigated in both an H24 state and an aged state. Whereas the very high initial strain-hardening rate decreases monotonically with strain for the H24 samples, the annealed structure exhibits a striking increase in the strain-hardening rate.

PROTECTIVE TREATMENTS FOR AZ31 Mg ALLOY

2006
The protective performances of different coatings for AZ31 Mg alloy have been evaluated in 0.1N NaCl and Na2SO4 solutions by recording the polarization curves and by EIS measurements. These coatings were formed in permanganate-phosphate or stannate baths as well as in hydroalcoholic solutions of silanes with a long alkyl-chain (e.g. octyl and octadecyl-
